 * Homework 4 - Potentiometer reading using STM32 blue pill
 *
 * NOTE:The real firmware was written in STM32CubeIDE (HAL) 
 * and is loaded into Wokwi as an .elf file.
 *
 * Wiring:
 *   Potentiometer: VCC -> 3.3V, GND -> GND, SIG -> PA7 (ADC1_IN7)
 *   LED: PA0 (TIM2_CH1, PWM) -> LED -> resistor -> GND
 *
 * How it works:
 *   ADC1 reads the potentiometer (12-bit, 0-4095). The value is shifted left
 *   by 4 bits to scale it to 16 bits and written to TIM2->CCR1 (period 65535),
 *   so the PWM duty cycle follows the potentiometer position.
