We Just bought this HC-Sr04 ultrasonic ranging module, and we would like to use it as an obstacle sensor, but we have a hard time on the program part of it. we thought it would be as easy as sending LOGIC 1 to the trigger pin ang receiving LOGIC 1 to the echo pin but it's not. do anyone have an experience on this sensor using it with PIC?
