What is EE 109: Pulse Width Modulation Basics about?
Pulse width modulation (PWM) controls the duty cycle of digital outputs to produce average analog voltages or power levels. It is commonly used to control devices like motors, dim LEDs, and set power levels in appliances. Microcontrollers generate PWM signals using timers and control registers to count up to a threshold value that determines the pulse width. Setting the pulse width modulates the average output voltage or power.
