+description			= "Chapter 4: Analog LED with PWM"
+long-description		= """Building smooth breathing LEDs and flowing light bars with hardware PWM on the
+Raspberry Pi Pico using Ada. From jittery duty cycles to perfect linear dimming - guided by the Voltcraft MSO-5102B
+oscilloscope and a deep dive into PWM slice mapping on both Pico 1 and Pico 2.
+
+In this chapter we create a reusable Pico.Analog package for PWM-based analogue output. We start with a classic
+breathing light, then move on to a flowing light bar. Along the way the MSO-5102B reveals the real behaviour of our
+code, and we discover (and fix) a subtle bug in the experimental RP2350 HAL.
+
+Contained in Chapter 04 are:
+
+1. Pwm			       - Original PWM sample from Jeremy Grosser
+2. sketch_04_1_breathing_light - Chapter 4.1 Blink internal LED
+3. sketch_04_2_flowing_light_2 - Chapter 4.1 Project Meteor Flowing Light
