If you are an electronics engineer or a beginner and want to build an obstacle avoidance robot, you need to first learn how an obstacle avoidance system works! which makes this project of ours super important, because in this project we are going to interface a HC-SR04 Ultrasonic Distance Sensor module with ESP32 and we are going to know every little detail about the module, which is a key component of any obstacle avoidance or detection system.
