I'm trying to create a small project where I have 2 composite video outputs and 1 monitor.
To switch between the 2 sources (no sound - only the yellow video cable), I was thinking using the relay module (https://www.espruino.com/Relays) and connect it as:
Output to monitor: K1 Pole
Output from source 1: IN1
Output from source 2: IN2
Ground / shield from the 3 cables would all be connected.
Could I've use the relay module to handle the video signal or would the module generate to much noice?
