Ultrasonic Sensor HC-SR04 With PIC Microcontroller

How ultrasonic sensor SR-HC04 works.
How Ultrasonic Sensor Works

An ultrasonic sensor is a very useful sensor that measures distances with sounds. We used the PIC16F628A microcontroller for this project. This microcontroller has TMR1 which we are going to use. We need 2 I/O pins for TRIG and ECHO pin. For showing distance, we used an LCD. For more information about the LCD library and usage click button below.
