From understanding the WS2812 protocol to writing our own PIO code and creating colourful animations – everything you need to make NeoPixels dance with Ada on the Pico.

Chapter 4 – Analog & PWM

In this chapter we create a reusable Pico.Analog package for PWM-based analogue output. We start with a classic breathing light, then move on to a flowing light bar. Along the way the MSO-5102B reveals the real behaviour of our code, and we discover (and fix) a subtle bug in the experimental RP2350 HAL.

Chapter 5: Controlling an RGB LED with PWM

Extend the simple LED examples to full-colour control with an RGB LED. Create a reusable Pico.Analog.RGB_LED package and explore two sketches: random colours (using the embedded runtime) and a smooth colour-wheel transition.
