- D2 is the IR emitter LED, wired in series with current-limiting resistor R2 directly across VCC/GND — it's always on, flooding the area ahead with IR light. - D1 is the IR receiver (photodiode/phototransistor), in series with R1 forming a voltage divider. The midpoint feeds the + input of comparator U1. - RV1 (10k trimmer potentiometer) forms a second divider between VCC and GND, with its…
