Sonar range finder using PIC16F88 Microcontroller
The PIC sonar range finder works by transmitting a short pulse of sound at a frequency inaudible to the ear (ultrasonic sound or ultrasound). Afterwards the microcontroller listens for an echo. The time from transmission to echo reception lets you calculate the distance from the object. PIC Sonar Specification Range ~5cm – 300cm Accuracy +/-3cm …
