⚙️In this lesson we will learn What is HC-SR04 Ultrasonic Sensor .
It is a very affordable proximity/distance sensor that is mainly used for object avoidance in various robotics projects.
It essentially gives your Arduino eyes / spacial awareness and can prevent your robot from crashing or falling off a table. It has also been used in turret applications, water level sensing, and even as a parking sensor.
✅After upload well the code to V4.0 board, then open the serial monitor. When place an object in front of the ultrasonic sensor (from near and far), it will detect the distance of object. The value will be displayed on the monitor.
