Hello all. One of my ongoing projects is staircase lighting using an Arduino Uno and a TLC5940. The trigger at the top of the staircase will be a PIR sensor. At the staircase bottom the trigger will be an IR beam break; the receiver of the beam will be a TSOP1738. Originally I used the IR library f…
