This version has higher resolution on the joystick axes, and the layout of the code isn’t slightly terrible. went through a second iteration of hardware for this project with a Teensy 3.1.
After connecting the rudder, elevator, aileron, and throttle signals on the receiver to an Arduino, a simple bit of code and the UnoJoy library allows any Arduino and RC receiver to become a USB joystick. Since a receiver simply outputs signals to servos, this provides a vastly simpler interface for an Arduino to listen in on. Normally, a USB simulator adapter plugs in to a 3.5mm jack on the transmitter used for a ‘buddy box’, but had an extra receiver sitting around. Buying one of these adapters would mean a week of waiting for shipping, so did the logical thing and made his own. The usual way of using an RC transmitter with a computer is to buy a USB simulator adapter that emulates a USB game pad through a port on the transmitter. has been spending the season with RC flight simulators for some practice time. He had been using an old Xbox 360 controller, but that was really unsuitable for proper RC simulation – a much better solution would be to use his normal RC transmitter as a computer peripheral. It’s winter, and that means terrible weather and very few days where flying RC planes and helicopters is tolerable.
