This repository contains the source for a photo booth driven by an Arduino-based intervalometer connected to a Canon EOS 350D camera. I put together this project for my friends' wedding reception in March 2015, in lieu of them renting a hugely expensive photo booth from a vendor. Instead of using a photo printer, I used an eyefi Wi-Fi SD card to automatically upload photos to flickr, so photo booth users could see their work on their smartphones soon after taking a photo. The reception attendees had a great time with it: see for yourself!
Here's an illustration of the circuit:
And here's the circuit as assembled on a prototyping board:
This project assumes the following hardware components:
| Pin | Component |
|---|---|
| 3 | LED |
| 4 | Arcade button microswitch, normally open |
| 6 | Two chained Adafruit NeoPixel Sticks |
| 10 | A single-channel optoisolator (autofocus) |
| 11 | A single-channel optoisolator (shutter) |
Digital pin 13 is also used for controlling the built-in surface mount LED on the Arduino Uno. The LED is used for debugging purposes, and is not required for normal operation.
The sketch requires the following libraries:
Upload the sketch to your Arduino Uno or compatible micro controller (see the official Arduino IDE documentation for detailed instructions).
