This is the indicator light that says whether you are rehearsing, transmitting or both.

Design

This light is controlled by an Arduino using GET requests over ip, this then triggers the corresponding relays.

You send commands to it in the format of <IP address>/?[request].

The code and schematic can be viewed here.

Relay control get requests

  • Turn on rehearsal light - <IP address>/?rehearsal_on
  • Turn on transmission light - <IP address>/?transmission_on
  • Turn on both rehearsal and transmission light - <IP address>/?rehearsal_transmission_on
  • Turn off both rehearsal lights - <IP address>/?rehearsal_transmission_off
