Reply to "IR or Optical Sensors"

ken's trainsOGR Forum Member

I get that Clack, what I'm not sure of is how the sensor LED is connected. Is it the same as for the emitter LED (i.e., + to anode & - to cathode; where the + lead on my ohmmeter goes to the anode)? And do I have that connection correct? Also, should I see a positive voltage on the anode (to cathode) output (on the module) for both?

If all that is true, then I can make certain I have the correct connections with just my multi-meter. How about the heat from soldering iron damaging the LEDs?

Thanks for your suggestion.
