Hello Michael,
Thanks for the wonderfull PDF tutorial..
In your’e tutorial, you using an Arduino Mega.
I’ll have an Arduino Uno, can i use the same code or do i have to buy an Arduino mega for it?

tnx allready,
Bert

Hi,
I am asking for help if possible. I wish to run High Speed Trigger using a keypad rather than buttons. I have tried to change the code without success. Is anybody able to help Thanks.

I’m putting together my Arduino kit so I can build my own drop trigger. Question; Can it work with my Nikon D60? It has a remote trigger, (ML-L3 Wireless Remote Control (Infrared). If so, do I have to make changes to the codes?

cheers simon
will give that a go .. just gotta swap my mega out for a new 1 first … was out after dark last weekend with v2 a bunch of waterbaloons, party poppers, flour, glitter and stars lol all ready to play and i found the flash problem .. brought the box back in to adjust the delay defaults ..then when i went back out i plugged the 24v power lead into the shutter release on the box by mistake lol ops (that will teach me for not using diff plugs hehe) have not tried the valves …got a lil distracted by the DLW. Ooo and a lil canon powershot sx50 hs i brought to play with moon pics cause of the huge zoom its got 🙂

Been there done that, killed a mega during the build. Giving me some ideas with the flour & glitter, did blow up a balloon while having a smoke the other day :-). Now looking for a cheap air rifle to really test the sound trigger and destroy some fruit.

Hi Chris, i checked through the new v2 and took 2 new lines and added them to the original version i am using. check through the new code and put these 2 lines in the same place in original.
PeizoValue = 1;
LightningDetectValue = 1;

Worked for me. Are your valves firing independantly or all together? Might try a separate optocoupler for each (only have 2)

Hi all,
Thanks for the new sound trigger code Micheal, had to add the 2 lines to the original code because the v2 wouldnt let me alter the flash delay without saving and restarting the box but working well.
My solenoids wont work independantly either, i am assuming its my wiring (had to put a transistors in) maybe flooding the optocoupler with light on the output side??? but looking through the code i cant find reference to the a-b delay, this is probably all down to me being new to both coding and electronics?
Thanks again Micheal, would not have had so much fun if i bought one off the shelf, might be frustrating at times but enjoy the challenge and getting some good results.

Hi Michael,
I found that the code for multiple valve is confusing. My valve fired all same time and the delay between valve not working. mind to advise?

thanks 4 the new update ..works gr8 as long as u give it a lil while to reset itself (my testing time i was setting if all off to quick between trys and i guess it didnt have time to reset) … tip 4 others ..if like me u are very new to this arduino stuff and u need to make some big adjustments to the default values each time u turn the box on ! ( my sound threshold needed to be 850 but 200 is the default so took a lil while to adjust lol) the defaults can be set in the sketch if u adjust the numbers on the “float ValueArray” line … i know this maybe easy for sum of u … but i only just worked it out 🙂 thanks guys chris

First of all, sorry for the late respond.
I did managed to get it running after replacing the optocoupler and blowing the 5V power line.
Now I`m on my way searching for IR receiver’s components.
Next step will be to take the project to PCB.

Thank you very much for your support guys 🙂

@Simon: I have already had the pleasure of frying my atmega chip on an UNO by applying unrestricted 5v to one of the pins. I got lucky and didn’t have to replace the whole board.

@Maarten: I figured that could be the only solution. I like the idea of connecting to the power plug on the arduino itself since it already has a built in voltage regulator.

I guess its time to jump into the pool. I’ll start assembly this weekend.

Be careful connecting to 5v, fried my board when I was tinkering and put a 12v feed by mistake. Use 12v and a plug to the socket next to USB, this has a built in voltage regulator. I think I read the arduino needs 7-12v feed.

I’m pretty sure I’m gonna get a tomato to the head, but for the life of me, I can’t see where the Arduino is getting its power….I’ve looked over the detailed diagram tracing power. I’ve done word searches in the pdf file, but I can’t spot that crucial bit of info.

Maarten, had similar problem getting shutter to work, had to put in a small delay between open and close on sound trigger (20ms ? I think). Chris and I had a thread running on the arduino forum, read it through because we went down a few dead ends.

Hi Ric, built one of these a while ago and have the same problem with all valves going at once, be interested if you find a solution. also still have a problem with sound, it will trigger once then have to reset threshold or turn off & on before it will trigger again. Have found it to be more reliable wthout the ir on water drops, just disconnect and use the timers.

Hi Maarten. I can confirm that I’m having the message READY TO FIRE after each trigger.
On the lightning mode I was having the same problem and them I added that delay line and it start working.
On the sound mode everything is working.
On IR mode it’s working but not the way I expected. I’ve noticed that the trigger controls 4 valves, but they are aways on at same time. I have the optio. To put delay between valves AB, BC, CD, but they don’t change anything. The arrays that control those delays are not even mentioned on the main sketch. I’m having to learn the programming in order to alter it a bit.
I’ll get there one point. And I can post the sketch when it’s working. I need a help of someone how is good with Arduino Programming. Anyone available to help me?
Cheers

In order for me to diagnose where my circuit is failing, could you tell me if the LCD screen gives you a message when a trigger has occurred, for example after showing Lightning Mode / IR Mode READY TO FIRE!
I am trying to find out if I generate a trigger but its is just not going through to the shutter or if I just do not manage to trigger at all. I hope that makes sense.

No, not yet. I am planning to separate the flash and shutter control onto a solderless breadboard and use another optocoupler as I might have a duff one. I do not however want to start desoldering before have proven I can make it work with a new chip.

How are you getting on?

I cannot help you with Fritzing but I would imagine you will run out of space really quickly if you want to have your board sit over the Mega. I have used a strip board and although I am sure you can make a lot better use of space than I have, my board is approximately twice the size ov the Mega.

Hi.
I’ve wired my second valve and I’m having a problem setting the delay between the two (A and B).
According to the Sketch, I could see that the parameters “VALVE AB DELAY” , “VALVE BC DELAY” , “VALVE CD DELAY” are related to the “DescArray[12]” , “DescArray[13]” , “DescArray[14]”.
But I didn’t find a line on the Sketch calling these Arrays.
I suspect that is the problem.
I’d like to ask Mr Ross how do we set this delay between the valves?

P.S: I’ve fitted a reverse biased diode on my solenoid valves. Would this be the source of my problem?

Thanks to all

Ha! As expected, my dodgy soldering was to blame for the IR/Sound selection not working. So I might be testing soon as well!

Thanks for the tip on Arduino power supply; it boots up nicely on its own now. I downloaded Fritzing as well but decided just to get a strip board and design/solder as I went along. Now that disorganised method may have caused an issue with the task selection because now matter where I put the IR/Sound selector, it keeps giving me the message ‘waiting for sound….’ I have swapped switches but to no avail and my wiring seems to follow the the diagram properly.

I’m looking forward to seeing your photos. I also will be using the Canon 100mm macro lens but with 1 x 580EX and 2 x 430 EXII.

Hi Maarten.
In order to run your unit off USB you will need to supply arduino with 5v from your circuit board (make sure you jump from the 5 volts track on breadboard). You have to place a jumper wire from 5v + to Vin on aduino and a jump wire from 5v – to any GRD pin on arduino.
When I was wiring my 16×2 lcd I had to change pins acording to the one I used.
Hope this will help.
I’m also making a PCB of the mross circuit using a little cool program called Fritzing. Free to download and easy to use. You can etch your on PCB’s and make te breadboard mess more clean, organized and more reliable connections.
I just finished wiring my second valve and will test today and tomorrow using a 100mm macro canon and 2 flashs ex550 canon. I will try to post then if they come out good.
Need’s lot of patience and dubby.

For the EXROM.h issue I posted a query on the Arduino board and was reassured, as you say, that it makes no difference as long as everything compiles properly. It has been an almost torturous road to get to even the initialisation sketch . I am building the 24V version with a 20×4 screen and was not getting anywhere so I decided to start again but solder everything. On reaching the initiation phase again nothing happened and it was only this morning at 5 am that I realised why. By adding the HelloWorld code I used to test the screen, copied from: http://learn.adafruit.com/adafruit-arduino-lesson-11-lcd-displays-1, to the initiation script I am finally making some progress. It initialises now and I am currently trying to figure out if I have my switches properly wired up as I seem to have trouble selecting the correct functions.

You are more advanced that I so unfortunately cannot help you with your query.

I will remember you extra delay when I get that far.

Does your unit start and work without a USB connection to your computer?

Hi Maarten.
The word EXROM.h does not need to be highlighted, and in my case it still in black. It happens because it doesn’t have the file “keyword.txt” made for it, and this shouldn’t be a problem.
I’ve done a 12v version using a 16×2 LCD. Start testing yesterday. it’s getting good.
I had to add the delay line bellow: (find Lightning Sequence Void) to help reset the shutter. Going straight from “HIGH” to “LOW” wasn’t happening and I decided to add this “delay(1)” in between. Hope it works for you.

”
// Release the Shutter
digitalWrite(ShutterTrigger, HIGH);
delay(1);
digitalWrite(ShutterTrigger, LOW);
”

But I have another question:

On the IR MODE, the Flash should be triggered just when the LAST DROP passes through the sensor.
In my case it’s triggering the Flash when the first drop crosses the sensor.
Not much of a problem, but I have to calculate the times of collision based on the “First” drop and not the “Second”.
Does anyone know how to sort this problem?

Thanks a lot.

Can you be more precise about the added delay line please. I am also not seeing the EXROM.h in the code highlighted in orange. Does your addition of the delay line relate to that?

Hi guys. Firs of all. Congratulation Michael. Your photos are great and your Precision Trigger simply the best.
I’ve just finished my unit following the tutorial. I’m using Arduino 0022 and loaded the Initialization Sketch first. The intervalometer works fine, but Sound Sensor, Lightning Sensor and IR Sensor are working only on the first time I press the Launch. I’ve got all the libraries installed and the sketches uploaded fine. I’m wondering if could be a problem with EXROM not been able to record de values.??
I’ve noticied that the word “EXROM.h” my code are not highlighted in Orange like the other 2 libraries. I don’t know much about arduino programming and tried to understand the codes. Does anyone know what the problem could be?
I can’t wait to start playing. Help me, please!!!!
Thanks a lot..

Thanks Chris. I will have a look. There is a lot to say for keeping it simple and being able to reproduce Michael’s schematics to every detail so similar pin layout seems very tempting.

Many thanks for your kind and very prompt help!

Maarten

Thank you so much! I presume this is a like-for-like replacement in every sense of the word and everything works?

Unfortunately, I have no electronic knowledge to judge these thing.

Thanks,

What a fantastic project! Judging from the comments already posted, I am not the only one who is inspired by your work.

Like Paolo in the post below, I also cannot locate a source of the NEC Quad OptoIsolator (I’m in the UK) and am looking to find a replacement. Can you please advise?

hi Mr. Ross, I would firstly like to congratulate them for the tutorial on the trigger.

I am passionate about photography and would like to make the instrument following his directions.

Unfortunately here in Italy I can not find the two optocouplers NEC, I would ask you if you could kindly tell me
some alternative.
By the time I found two optocouplers TLP521-4-GB FTA TR 4 CH55V ISO2.5KDIL16 with pin equal to the NEC but with different electrical characteristics from those indicated by you

waiting for your reply …. I cordially greet

Paul

It works, had a go with water drops this evening and its great, problem with the I.R. not picking up the drops but i disconnected that and it ran very reliably just off the timers. Took a bit of time getting the delays right. Off to buy some balloons tomorrow then a rain dance to get some lightning to test it on.

Thanks Micheal, lots of fun hours ahead.

Nearly there, all up and running. Had to put a transistor in to switch the solenoid. Couple of glitches to iron out, sound will only fire once without restart, if I press the go button a second time it just fires flash/shutter without waiting for sound. Think a similar thing is happening with lightning detector (only works once without restart) but it will not open shutter, it goes through the motions and waits for light then back to start screen. I might try with a small delay in the program between shutter high/low.

Hi Chris, Thanks for the reply, I have done that but I can’t get it to work,Think I will give up and buy a stopshot, Have wasted enouch time and money on this obviously I am to stupid to be tackling this project.Cheers Kim

Hi Micheal. I have just about got everything together on my trigger,and I am attempting to load the code to my Arduino,But I get an error in the code ,the 1 off code and also the main code ,so I am unable to compile the code the error is as follows:”LCD Keypad” does not name a type,It is between the libraries list and set Arduino pins command .Can you tell me what I should put in there ? I have tried telling it what the LCD is but it will not work.Would appreciate any help,After all the time I have put in to get to this stage I am stumped, Thanks Kim

I’m looking for a retail source for a color mix-pack of 12V Indicator LEDs. Alternatively, if I were to use standard LEDs, would I use a resistor between them and the Arduino digital outputs? Of course, regular LEDs don’t look as nice as what you have used, so a retail suggestion would be appreciated.

For the solenoid, I’m going to start out with the 12V model from Jameco, but if I were to look into a Shako, which model number should I go with, PU220-AR? Are there any other model details. Thanks.

Solved my problem with the optocoupler not being able to handle 200ma for the solenoid, used a transistor to switch the 12v supply. Fried my Arduino while setting this up – connected 12v+ & 5v+ rails somehow so now waiting for a new one. I have ordered a sound sensor module as well to overcome my piezo problem.

Simon

Sorted the light detector (my mistake), sound detector not working properly, i dismantled the piezo and found that tapping or slightly bending the disc gave an output but sound had no effect – amplify it? I have snapped the wires off now so waiting for a new one!

Can get no trigger signal for the flash/shutter, board is working as i set the flash trigger to HIGH in the program to test it & got 3 volts on the pin.

Noticed in the program that exrom was not highlighted orange like the other 2 libraries used – problem?

Simon

I am in a muddle, spent 3 days trying to make it work. All switches and the lights work but i can get no reliable inputs or outputs, lightning detector is maxed out at 1023 and will go down to the high 900’s if i cover it completely, sound detector no response and without these i can not test flash, shutter & solenoids.
I have discovered (i think) my optocouplers cant handle 200ma on the out side by pressing the drain button and everything dims but no click from the solenoid, it will click direct from 12v circuit.
Changes i have made from the original are 5mm led’s & resistors for the lights and omitted the remote launch and 1 of the lamp control sockets. Reinstalled the program, should i reinstall the initialisation code?
Any ideas?

Simon

i am trying to get someone to do me a pcb for this system and thay are asking ???’s i not sure on 1. Current limit on opto-couplers (PS2532)
– Maximum collector-emitter current (output side) = 150mA per channel 2. Both sides of shutter trigger output are grounded 3. Valve trigger pins are tied together (valves controlled independantly by MCU?) 4. Drive strength of Atmega2560 pins for lights and lamp trigger
– Arduino website states that the 2560 can sink/source up to 40mA

if any one has ideas of what to do or would like to have a look at the digram that he has layed out you can email me at ttopee1@gmail.com when i get a lay out for a pcb i will let you know if i can get past the probs he keeps bring up

Up and running. Arduino, light sensor & switches working but no sound detection or solenoids & still more to check. And i did manage to blow a capacitor after your warnings.

Things I have found so far.
1. when i pushed the headers into the small breadboard most of the pins pushed back through their holder and didnt make, took a while to find.
2. had to install an older version of arduino software or i had problems with the exrom not being recognised.
3. Had to add power to the 5v & ground pins or the screen would not light up although there was power to the arduino from somewhere.
4. A decent soldering station is worth having over an ordinary iron.
5. Not sure about the large breadboard, i think the power lines only go half way. Had to put some jumpers in.

Hi Michael
Thank you so much for all the work u have put into this. It looks like it is probably 1 of the best systems available. so many functions. This will be my first play with bits that Hopefully don’t go fizz. I now have all the bits and have read your instructions so many time i almost fell like i know what im doing.
two tiny things
1,like simon above i couldn’t find the power to the Arduino (guessing its the R+B wire on the top left of the little board that you were coming back too 😉 that goes to the empty 5v pins on the wiring diagram ) 2. A missing 100k resistor on the part list.
I’m about half way through the build and cant wait to try it out.. do u have a vid of your whole rig in action ??
once again thank’s for showing us with no clue at all how its made 😉

Hello again, all parts have arrived and the build has started. question 2:- my Canon 7d has 3 pins, do they all need to be connected, the tutorial suggests i only need 2? (It will be used in manual focus only) Found this site with pin/plug configurations for most cameras www.doc-diy.net/photo/remote_pinout/
All going well but i need to order more wire, surprisingly i have used 11 metres already.

Simon

I’m in the process of building something similar for dedicated water drop photos only. Do you have any results worked out between the different ($ vs $$$$) solenoids? I found some very cheap (just $2.75 each) 12v ones @ www.sciplus.com (they appear to be removed from Keurig coffee makers). There seems to be a good supply of these on eBay as well. I haven’t got all the parts I need to put the entire thing together yet so I can’t say how my bargain ones will actually work out in practice.

that error script is what i get after the exrom is added into the lib. assuming i know little here is wring as i only just started and made the set up, I have no no experience is with the Arduino and the software (1.0.1) and i can get things out of the getting started with arduino book here is what i get if i leave out the exrom

All parts ordered, some of which will take a while as they are coming from china. I will let you know how i get on as I will test your theory of somebody with little or no electronics knowledge being capable. For anybody in the uk i found a useful site called bitsbox to supply a lot of the electronics components in sensible quantities and prices.
Thanks again for doing all the hard work.

Hi Micheal, Thanks for a great project,I am keen to have a go at making one ,I was just wondering if you would be able to tell me if it will work with a Sony a65 and if so what output for the remote cable should I use ? The 2 wire or 3 wire option?. Thanks again Cheers Kim
