PWM Fade 17

Control LED brightness, buzzers, and motor driver speed inputs.

Source code and build tools are available in the protected platform workspace.

How it works

Create a smooth analog-like output using PWM.

  1. Use a PWM-capable pin from the map.
  2. Connect an LED with resistor or a motor driver enable input.
  3. Increase level until it reaches 255.
  4. Reverse stepSize to fade back down.
