RC Remote Control Raspberry Pi Pico

The Raspberry Pi Pico does not come with any kind of wireless build-in, but that doesn't mean you can't control it without wires. You can easily add an RC controller such as ones used to control RC model Airplanes.

In this video I will explain about the type of controller I use and how you can connect the 6-channel receiver to a Raspberry Pi Pico and read the input signals using PWM.



The model I used is the Flysky FS-i6 which is relatively inexpensive controller for RC model planes. Although designed for model airplanes it can be used with other models and in this case to send signals to a Raspberry Pi Pico. You could also use other types of controllers such as those designed for cars or boats, as long as they provide a PWM output pulse typically used for controlling servo motors.

In the video I show how I used a logic analyser and digital oscilloscope to check the signal and how I set about creating the code to detect the PWM duty cycle on the Raspberry Pi Pico. This can then be used to control other devices such as robots or animatronics.
