long-description		= """Learn how to drive active and passive buzzers with the Raspberry Pi Pico using Ada.
From simple doorbell switches to PWM-generated sweeping alert tones - including hardware tips with flyback diodes and
oscilloscope measurements.

In this chapter we connect both active and passive buzzers to the Pico. We start with a simple button-controlled
doorbell, improve the passive buzzer with bit-banging, and finally create a clean sweeping alert tone using the Pico's
PWM hardware. We also look at inductive-load protection and why a diode is essential.

Contained in Chapter 07 are:

1. sketch_07_1_doorbell.adb	- Chapter 7.1 Doorbell with active buzzer
2. sketch_07_2_alert.adb	- Chapter 7.2 Alert with passive buzzer
3. pwm_alert.adb		- Use PWM to drive an passive buzzer
4. buzz_and_blink-main.adb	- Use tasks to drive both a buzzer and an LED
