I trust you would have actually made this circuit and checked it out. An modification is suggested. The output of the amplifier can be provided to a LM 3914 and the distance can be measured too. Could be useful while backing up the car. Keep up the good work. I trust you would have actually made this circuit and checked it out.

At the same time, I would like to suggest the following modification. After the signal at the receiver is amplified, we could effectively employ a LM 3914 to tweak the output to indicate the distance with a little calibration. Good one. Keep it up.

Am doing my min project cöncerning ultrasonic switch bt am facing the problem concrng the following cmpnt: relay switch 6volt 200 ohm, ceramic capacitor 560n, variable resistor 250k and 18k potentiometer, 680Pf, plz help me for the equivalent of these component if supply needed is 9v.
