Detecting obstacle with IR (Infrared) Sensor Raspberry Pi 3

Concept: IR (Infrared) Sensor IR (Infrared) Sensor works by emitting infrared signal/radiation and receiving of the signal when the signal bounces back from any obstacle. In other words, the IR Sensor works by continuously sending signal (in a direction) and continuously receive signal, if comes back by bouncing on any obstacle in the way. (more…)
