Swift Without Screens: Powering Connected Devices

on YouTube ↗19m

" summary

Swift runs on a Raspberry Pi to drive a battery robot car called TryBot Model 3 using an L298N motor driver, DC gearbox motors and an HC‑SR04 ultrasonic sensor. Code uses the swiftie GPIO library and a remote build flow via swish with precompiled Swift ARM binaries installed through apt. Four GPIO pins GPIO 17 22 23 24 toggle according to the L298N truth table to go forward, back and turn. The car demonstrates working motor control and a planned object‑avoidance upgrade using distance measurements from the HCSR04.
