I’m using a 315 Mhz, 12 channel wireless remote and relay control to operate some 12 vdc motors. It energizes the relays to turn power on the system, choose motor direction and start the reversible motors. Every thing works well but I need positive feedback to prove the motors and relays are in fact on or off and I need to figure out how to put Led’s on the remote and light them up and stay on as long as the relays and motors are energized. What is a simple way to do this?
