4. MODULES IN DETAIL

In the following, all modules available on the Explorer Board are explained individually with sample codes. Here you can download all sample codes and

libraries, as well as a sample code that links all modules together.

For the use of some modules, external libraries and a font file are used. Download the libraries and load them into the lib folder of your Raspberry Pi Pico.

Place the font file in the root directory of your Raspberry Pi Pico.

4.1 BUZZER

A buzzer produces a signal tone, similar to a loudspeaker. Unlike a loudspeaker, however, it is only suitable for a limited frequency range, so it does not

produce a good sound for reproducing music or speech. However, it is ideal for generating loud warning tones in the form of beeps. Whenever an electrical

device generates a warning tone, it is almost always a buzzer. For example, in alarm clocks, smoke detectors or the seatbelt reminder in cars.

The buzzer is connected to GPIO pin GP27.

# Load libraries

from machine import Pin, PWM

buzzerPin = Pin(27)

buzzer = PWM(buzzerPin)

while True:

# Activate buzzer for 1 sec

buzzer.freq(1000)

buzzer.duty_u16(1000)

sleep(1)

buzzer.duty_u16(0)

sleep(1)
