Train Driver Firmware

Summary

Bare-metal embedded Rust firmware for the Train Driver project. Reads two potentiometer inputs via ADC, maps them to percentage values, and drives PWM outputs to control motor power and LED brightness. A health indicator LED toggles at a configurable interval to confirm the system is running.
