Control-system firmware for a compressed-air powered race car — no fuel, no electric motors. Student project by team FLUJD · SPŠ techniky a dizajnu, Poprad 🇸🇰
Two ESP32-S3 chips (master + slave) talk over UART and together run the drivetrain, steering, tilt detection and diagnostics. Built with PlatformIO — one repository, two firmware images. Every part, circuit and line of code was designed and built by the team.
