Firmware

Expected Behavior

• Configure PWM on selected GPIO.
• Sweep duty cycle from low to high.
• Optional: print current duty cycle to serial.

Physical Test Procedure

1. Start with low duty cycle.
2. Observe LED brightness.
3. Measure average voltage for several duty cycles.
4. Record whether visual brightness matches expected trend.
