Ever wonder how robots detect objects around them? In this clip from the SparkFun Inventor’s Kit for MicroPython, we explain how ultrasonic distance sensors use sound waves to “see” their surroundings, just like bats do with echolocation.
The sensor in your kit emits high-frequency sound pulses, then measures how long it takes for the echo to bounce back. By calculating that time, it determines exactly how far away an object is. It’s a simple but powerful way to give your robot awareness of the world around it.
