None, it send an pwm/ppm signal so you are able to read it. It is just software. If you doesn t have a lot of experience see the function pulseIn from the reference
Yes I know that it uses PPM. But RC controller use a 2.4 GHz to send signals, so I need a 2.4GHz receiver, right? What receiver could I use? Could I use any 2.4GHz receiver or I need a specific receiver?Thanks.
...and what pin would I use for RF frequency?that reference uses a pin to read the pulse. Would an xbee work?My "first" Arduino project will be a RC car purchased, ripped apart, replace everything inside of it with Arduino, better motors, etc, and eventually loading a NERF dart gun, or an airsoft into it, so ive been researching this same thing. I was about to drop down to Bluetooth, but I would very rather not.If I got a RF controller for a car or quad(for the extra buttons), could I get one xbee shield and be "set"?
