  "long-description": "Learn how to drive a common-cathode RGB LED using the RP2040's PWM peripherals.\nThis chapter introduces a reusable Ada package for colour control and demonstrates both random colours and a smooth\ncolour-wheel gradient.\n\nExtend the simple LED examples to full-colour control with an RGB LED. Create a reusable `Pico.Analog.RGB_LED` package\nand explore two sketches: random colours (using the embedded runtime) and a smooth colour-wheel transition.\n\nContained in Chapter 05 are:\n\n2. sketch_05_1_random_color_light.adb   - Chapter 5.1 Random Color Light\n3. sketch_05_2_gradient_color_light.adb - Chapter 5.2 Gradient Color Light\n\nRead the full tutorial at [Chapter 5: Controlling an RGB LED with\nPWM](https://pi-ada-tutorial.sourceforge.io/pico_ada_c05_rgb), [GNATdoc\ndocumentation](https://pi-ada-tutorial.sourceforge.io/gnatdoc/pico_ada_c05_rgb/), [SourceForge\nrepository](https://sourceforge.net/p/pi-ada-tutorial/code/ci/master/tree/pico_ada_c05_rgb/)\n",
