This one is for Stan.
I have been playing with the LED replacement lights and finally gotten back to the IR detector that you so kindly outlined for me. I have all of the components (bridge rectifier, DC-DC pwr supply, IR detector module, & 5v relay module) you suggested. I have been playing with limited success. I couldn't get the relay module to trigger properly because the sensitivity of the IR module couldn't be throttled down. With further investigation I discovered that the output of the IR module 'trigger' was 5v (or whatever VCC was set at) when there was NO detection. When detection occurred, the output went to almost zero. I had connected the IR module 'out' to the relay module 'in', and I believe that it impacted the IR module function. Once I removed IR 'out' from the relay 'in', the IR module sensitivity was easily adjusted. Soooooooooo, how do I connect the IR module to the relay module. I checked the relay module jumpered pins labeled COM & GRN, and they are not connected to the GRD pin next to the VCC pin. I am afraid to connect the IR 'out' to the relay COM & GRD, but that seems like my only option.
Please help.
Ken
