Raspberry pi with Python for Robotics 9 - Adding HC-SR04 Distance Sensor
Basic Raspberry Pi Robot Car Playlist: • Raspberry pi with Python for Robotics...
In this python tutorial video, we take our raspberry pi robot car, and we add the HC SR04 ultrasonic distance sensor to it. The idea of the distance sensor is to relay some waves out, time how long it takes for them to come back, and, then, using the known constant of the speed of sound, we can derive the distance of the object that the sound bounced off of.
