Re: Ultrasonic sensor help needed
My suspicion is that you're reading the supply voltage. Particularly because the sensor has a maximum range of 255 inches (2.55 volts). But it's fed with about 5 volts...
Little solder globs can do that sort of thing. As can little 'hairs' of copper wire. and so on.
