###Bind
Make sure to follow the following procedure: press the bind button, apply power and then release it after 1sec. The LED should be blinking fastly indicating a bind status and then fixed on. It's normal that the LED turns off when you press the bind button, this behavior is not controlled by the Atmega328.
###Protocol selection
For serial, leave all 4 selection pins unconnected.
For PPM, connect 1 to 4 of the selection protocol pins to GND.
The protocol/mode selection must be done before the power is applied.
