<p>Need to give credit to ticktock for the original idea.</p> <p>The indicator uses a green 1206 SMD LED and 22k-ohm SMD resistor. Wanted low current draw and low brightness from LED.</p> <p>Obviously the tiny window should be printed with a clear or light colored filament.</p> <p>Working with SMD components can be frustrating, and you could ruin your IR_Sensor board. I glue the SMD parts in place on the end of the IR board near +5V and Signal pin-outs, then carefully solder. Will add wiring diagram image as well. SMD Soldering at Home . . . Google for: wire wrapped around end of soldering-iron tip to reduce tip size.</p>
