The need to design the board was to run a class on Aeromodelling.
The setup was as such where I can demonstrate on a projector how to fly an airplane, then the Transmitter can travel through the class as each student pilots the craft, while others watch.
An Arduino Pro Micro connects to a 6 Channel RC Receiver to emulate a joystick.
Use this project and its PCB to practice on a Flight Simulator. The Arduino Pro Micro can read the values of each of the channels and can be interfaced to other projects as well.
Not all RC receivers support SBUS/PPM outputs, and most of the time, the signals are available on individual channels. (CH1-CH6).
The Device will show up as a Joystick on the Laptop. You can then pair your RX-TX and the positions of the controls can be relayed to the computer.
