If you don't want to deal with the delay between the ESP8266 triggering the camera and the camera taking the picture, instead use a darkened room, long shutter exposure and trigger the flash with the ESP 8266 instead, triggering the flash is pretty much instantaneous !
I've tried that in the past and if you can get a truely dark room it is certainly possible but you also sacrifice being able to see what is going on (something very useful when shooting macro things at high speed haha). Plus I'd still have to deal with timing the flash via the sensor.
Technically sure, it's a Wemos D1 Mini which uses an ESP for its processor. But at this point Arduino seems to be a generic term for any microcontroller than can be programmed using the Arduino IDE. I figure if the code an wiring can be used on a regular Arduino board then it really doesn't matter what board I use as long as others can follow along :)
ItKindaWorks i never heard someone call an esp by the name Arduino... I use the esp a lot for all my projects and love these little things.. too bad the esp32 chip is so bulky and difficult to solder.. the D1 mini pro is also sweet..
Well perhaps I'm in the minority but given the vast number of Arduino compatible boards at this point I feel like it doesn't matter too much. There are so many compatible boards apparently there is a wikipedia article for it haha en.wikipedia.org/wiki/List_of_Arduino_boards_and_compatible_systems
From that wiki: Although the hardware and software designs are freely available under copyleft licenses, the developers have requested that the name "Arduino" be exclusive to the official product and not be used for derivative works without permission. The official policy document on the use of the Arduino name emphasizes that the project is open to incorporating work by others into the official product.[2] As a result of the protected naming conventions of the Arduino, a group of Arduino users forked the Arduino Diecimila, releasing an equivalent board called Freeduino. The name "Freeduino" is not trademarked and is free to use for any purpose.
By the way I think we should ALL move away from the Arduino and start using the ESP's... if you need more than 1 analog in use the ESP32 or a multiplier.. if you are ok with 1 analog in I see no reason not to use the ESP's... and if you are used to the Arduino Uno just use the D1 (big one) that even looks like the Uno :) I wish all 3d printers would start using the ESP chips.. they are faster, have more memory, build in wifi etc...
This is very interesting and I think I want to try this with my camera. In doing a quick test on my remote trigger (similar to yours), it seems that the circuit provides ~3.5V on both signal lines and drops out when the button is pressed. So, on my camera, the Canon T3i, the trigger is *removing* the voltage. I will have to play a bit more to be sure. I think I have a sacrificial plug that came with another device that I can bastardize for this.
Another awesome practical video. If I could make a recommendation. Could you show a schematic of your circuit? Even if it is just a pencil paper picture would be helpful. The ir glasses is a great idea.

That's an esp8266 right? Not an Arduino.

Thanks! If you take a look in the description, there should be a link to the code and the breadboard layout/schematic.
gonna mount this in my toilet bowl :D
D:
That is a fantastic idea!
At first I thought those were Jell-O shots !
If only! ;)
