This project is a simple autopilot for Atem video switchers from Blackmagic Design. It is just like the previous project “Tally light ESP32 for Blackmagic ATEM switcher” based on the ESP32 microcontroller. Also for this autopilot, we again use the M5StickC development module (from VNGsystems) that we program with the Arduino IDE, but you can of course use any other ESP32 development board.
