Hi everyone!
Chapter 2 of my Raspberry Pi Pico + Ada tutorial series is now live: Button & LED – two working sketches that turn a simple LED into a responsive switch and a proper toggle-style table lamp (with software debounce).
Both examples worked first time — a nice change after some runtime experiments in Chapter 1 
- Direct port of the Freenove C example (on while pressed)
- Table lamp version (press once to toggle, with debounce)
Full write-up, Ada source, photos, GNATdoc links and Alire crate here: Chapter 2 – Button & LED · Pi Ada Tutorial
Repository: Pi Ada Tutorial - Browse /Alire at SourceForge.net
Alire crate (soon): pico_ada_c02_button_and_led
Feedback, questions and pull requests very welcome — especially if you spot ways to make the Ada code even more idiomatic!
Next chapter is already in the pipeline… and yes, I’m planning to turn that LED bar into a proper red Cylon eye scanner 
Cheers, Martin
