UncleMike here again;
I am having a problem (yes I read the post by angpal59, and have not found any other posts relative to this ) getting a signal from my ping unit.
I have hooked a 3 wire connector (as supplied in the kit blk,red,wht) black-5v, red- grd. white to trigger and a separate white to echo (by the way DJ in the ultrasonic tutorial video says the middle pin is ground but that is not how the board is labeled) I have set the trigger to D0 and the echo to D1 and the servo to D2, (servo responds correctly)
the panel shows the changing servo settings but the distance shows 20 and does not change when I change the distance my hand is in front of it, nor does the graphic show "pings"
