Hey guys,
we're using a Sharp IR Rangefinder (GP2D12F) and we want to try it out before connecting it to the microcontroller. So we plugged in a 5V supply to the red wire of the IR, grounded the black wire, and checked the volltage output between the green wire and ground.
unfortunately, it stays at an ~ constant of 2.9V.
Can we test the IR sensor this way or are we doing something wrong? we checked that 5V are being supplied (just in case you ask).
