blink example through explicit pin control to using an external LED, plus thoughts on the elegant (but still
experimental) Ravenscar profile.
Starting simple with LED blinking in Ada - internal LED, external LED with proper renaming, and a look at why Ravenscar
looks so clean (even if it's not quite ready for everyday use yet).

long-description = """Building a smooth flowing LED bar on the Raspberry Pi Pico with Ada - from a simple
chasing light to a proper menacing Cylon scanner effect using real-time delays.
In this chapter we turn ten LEDs into a flowing light bar. We start with the basic Freenove example using an array of
RP.GPIO.GPIO_Point (aliased limited tagged types). We then improve it with a pre-calculated sine-harmonic timing table
to create a realistic Cylon scanner - all done with Ada.Real_Time and zero floating-point at runtime for perfect
jitter-free movement.
Contained in Chapter 03 are:
1. Sketch_03_1_Flowing_Light - straight port of the classic flowing light
2. Cylon_Light - the final dramatic Cylon scanner with organic easing
3. Cylon_Light_Float - Floating point version of Cylon_Light

This crate extends the official pico_bsp from Jeremy Grosser with additional, reusable components. It is designed for
general use in any Ada project targeting the RP2040-based Raspberry Pi Pico and is not limited to the Pi Ada Tutorial.
It is developed in parallel with the [Pi Ada Tutorial](https://pi-ada-tutorial.sourceforge.io/) and therefore also
supplies the exact support packages used in the tutorial chapters. This dual role makes pico_xbsp equally suitable for:
* Standalone embedded Ada projects that only need the extra functionality, and * Readers following the tutorial who want
ready-made, well-documented building blocks.
Current content:
1. Pico.Analog - Analogue GPIO using Pulse Width Modulation (PWM).
1. Pico.Analog.RGB_LED - Analogue RGB LED control using Pulse Width Modulation (PWM).
2. Pico.UART_IO - UART Text Output (Input comes later).
All packages are supplied with complete GNATDOC annotations.
* [GNATdoc documentation](https://pi-ada-tutorial.sourceforge.io/gnatdoc/)
* [SourceForge repository](https://sourceforge.net/projects/pi-ada-tutorial/)
The crate will grow with each new tutorial chapter while remaining a clean, independent library.
