OK, so I’m going to make a remote control to my next robot. I want to connect a picaxe 28x1 to a Xbee and I have ben trying to find
some good examples but with limited success.
As the Picaxe operates at 5V, whilst the Xbee operates at 3.3V I understand that the signal from the picaxe has to be regulated. (not just the input voltage to drive the device).
Of Cause I could run both the picaxe and the Xbee at 3.3V, but that would just screw with everything else I'm gonna connect to it.
