In 7thexample, I will explain how to make a simple distance measurement system using the most popular HC-SR04 Ultrasonic Sensor. We will simply measure the distance and then print it on the i2c supported SSD1306 Oled display module. These examples will help you in getting started with the S...
the piezoelectric chip will vibrate, converting mechanical energy into electrical signals, and then it becomes an ultrasonic receiver. Ultrasonic sensor uses the principle of the piezoelectric effect to convert electrical energy and ultrasound into each other, that is, ...

In essence, the problem entails in reading an ultrasonic sensor HC-SR04 and display the output in your own way. I decided to display the output with an LED in PWM mode. The closer the object is to the sensor, the brighter the LED shines. ...
