Chapter 5: Controlling an RGB LED with PWM

#raspberry #pi #pico #rp2040 #tasking #light-tasking #ada2022 #embedded

Learn how to drive a common-cathode RGB LED using the RP2040’s PWM peripherals. This chapter introduces a reusable Ada package for colour control and demonstrates both random colours and a smooth colour-wheel gradient.

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.

Contained in Chapter 05 are:

sketch_05_1_random_color_light.adb - Chapter 5.1 Random Color Light
sketch_05_2_gradient_color_light.adb - Chapter 5.2 Gradient Color Light
