Introduction

This is a simple project that uses a PIC18F4431's ADC to sample an analog signal, which is used to control the brightness of an LED. A potentiometer is used to create an analog voltage signal, and the PIC reads the analog signal and outputs a PWM duty cycle corresponding to the voltage level. The PWM signal drives the LED, which will appear brighter or dimmer depending on the duty cycle.
