HC-SR04 Ultrasonic Sensor with ESP32 ESP-IDF
In this tutorial, we will learn how to interface HC-SR04 ultrasonic sensor with ESP32 using ESP-IDF. Firstly, we will introduce you to the ultrasonic sensor, then interface it with our development board and program it for contactless distance measurement using ESP-IDF. For demonstration, we will first measure the distance readings and print them on the … Read more
