Adjust the Color and Brightness of an RGB LED

A microcontroller is a digital device, but many real-world signals are analog. The microcontroller reads analog input signals by converting them to digital signals using analog to digital conversion (ADC). The microcontroller generates analog output signals using pulse width modulation (PWM).
