I have built a IR controlled light switch using the tsop 1738 IR sensor, 555 timer, D-flip flop (wired as toggle), and a 12 volt electromechanical relay. My question is how can I implement the use of a manual backup wall switch that allows me to turn the lights on and off but also still allow me to use the remote.
Essentially If I have the light turned on and then use the wall switch to turn it off, I should be able to press the button and the light comes back on. I've currently only been able to use the remote and it switches on and off perfectly, but when I try to include the wall switch as a backup I can't quite get it. I've tried wiring the light switch in series and in parallel with the relay. Any help would be greatly appreciated.
