  • 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?
