Basic IR Detector/Emitter:
parts:
R1 | 270 ohm resistor |
R2 | 10k resistor |
LED1 | Infrared LED |
Q1 | Infrared-sensitive photoresistor |
This is a very basic infrared detector/emitter circuit. One major downside of this circuit, is that ambient infrared light will interfere with
its detecting obstacles.
