USB Joystick Extender

[motorfiets]

Curious if your USB extender code could work for a joystick? I am wanting to wirelessly extend two potentiometers (maybe more?) over 915mhz.

• Feather connected to (2) analogRead sensors
  Transmitting the sensor data to
• Feather connected to PC using the Joystick.h library.

I have the code working perfect for a single AnalogRead sensor but I would like to have multiple sensors to the TX feather.

My code currently below:

}

Joystick.setZAxis(rudder);
