abrookfield:
i powered the arduino from the vdd pin(ground) and vss pin(+5v) of the pic..
and i connected the arduino gnd to the digital gnd..am i doing it wrong?..
vdd is normally +v, vss is normally 0v
sorry i got it backwards, anyway is the wiring supposed to be like this:
im having doubts on using the pic pin as gnd so using the supply gnd will do right?..
Well that drawing shows correct common grounding between the arduino and the PIC, but it also shows a permanent ground wired to the PIC input pin, which is certainly incorrect.
