[...] as soon as I use a 9v battery the ping sensor stops working. Everything else works.my guess is that the sensor automatically shuts off because the arduino regulator isn't doing a good job at regulating the 9v.Any ideas/solutions?
Ok I finally got it working, but its kinda unpredictable. Sometimes it works, sometimes it doesn't. The arduino does have a home-made shield on it. Could that be cause some kind of noise that messes everything up?
Anyways the arrow on the cap should be pointing toward the sensors/ servos right?
And is there difference btween µF and µ?
