the android app connects with the web app via webrtc communicates with the microcontroller via usb. one can also turn on the flashlight. if it's dark. github repo
to establish a webrtc connection one needs a signaling server. i implemented one in go. github repo
the firmware of the raspberry pico communicates with the android app via usb and controls the motors via pulse-width modulation. github repo
i built a 3d printed steering wheel with a raspberry pico and rotary encoder. in the future, i'll maybe use that instead of the xbox controller. github repo
