The Arduino code has built-in functionality for both Canon and Nikon infrared remote controls. To control the camera via Bluetooth, [AlxDroidDev] built a custom Android application.

The remote control is used to turn the Pi on. The Arduino reads the IR code from a remote and simply powers up the Pi.

I’ve designed two processor boards that can easily learn up to ten codes from an infrared remote control! There are 10x outputs that can be used to control external circuitry, such as a TTL or ...
