  "long-description": "Building a smooth flowing LED bar on the Raspberry Pi Pico with Ada - from a simple\nchasing light to a proper menacing Cylon scanner effect using real-time delays.\n\nIn this chapter we turn ten LEDs into a flowing light bar. We start with the basic Freenove example using an array of\nRP.GPIO.GPIO_Point (aliased limited tagged types). We then improve it with a pre-calculated sine-harmonic timing table\nto create a realistic Cylon scanner - all done with Ada.Real_Time and zero floating-point at runtime for perfect\njitter-free movement.\n\nContained in Chapter 03 are:\n\n1. Sketch_03_1_Flowing_Light  - straight port of the classic flowing light\n2. Cylon_Light\t\t      - the final dramatic Cylon scanner with organic easing\n3. Cylon_Light_Float\t      - Floating point version of Cylon_Light\n\nRead the full tutorial at [Chapter 3 - Cylon LED Bar: flowing light upgraded to a menacing\nscanner](https://pi-ada-tutorial.sourceforge.io/pico_ada_c03_led_bar), [GNATdoc\ndocumentation](https://pi-ada-tutorial.sourceforge.io/gnatdoc/pico_ada_c03_led_bar/), [SourceForge\nrepository](https://sourceforge.net/p/pi-ada-tutorial/code/ci/master/tree/pico_ada_c03_led_bar/)\n\n(The Cylons did nothing wrong. Humans created the perfect companion species and then completely messed it up.)\n",
