Re: Help! Analog Inputs!!
It doesn't really matter in this case, but when using an unsigned value, like analog inputs, you should use %u and not %d (the ADC conversion gives you a 10-bit value, 0-1023, so it should never come up as negative, but it's good to know in case you need a full 16-bit unsigned int).

Just make sure that the pot is properly connected (red + black leads to the outer leads on the pot, white to the wiper/middle lead) and you should have no problems. Our arm potentiometer got disconnected during testing and its value started creeping by 1 every few seconds, it was really weird. O_o
