Looking at buying a Mega 2650 to tinker with.
If I put a BT module on it to control via my android, would it be possible to have it read the G sensor values automatically, or no?
What are practical uses of this? Seems to me typing letters still take a reaction time (with how the keyboard autohides), versus having a control GUI where you just tap an arrow?

Also, when setup to get RC inputs of PPM using the diode method, is it possible to have the arduino send the PPM values to my phone, so that I can properly calibrate my code for the PPM values?
