The Raspberry Pi Pico W is a powerful microcontroller board built around the Raspberry Pi\u2019s very own microcontroller chip, the RP2040. You can check out a selection of RP2040-based microcontroller boards here<\/a> or keep reading to find out everything you need to know about sound output using the Pico W.<\/p>\n\n\n\n

Have you ever considered making a music player, creating an audio spectrum analyzer, or building a beatbox, but ran into problems playing audio using your microcontroller? Well look no further, this is the article for you!<\/p>\n\n\n\n

Here, I will introduce you to the universe of Pulse-Width Modulation (PWM), communication protocols for the Pico W, and how take advantage of the Pico W\u2019s wireless connectivity.<\/p>\n\n\n

Pulse-Width Modulation<\/h2>\n\n\n\n

One way to play sound on the Pico W (or any other microcontroller for that matter) is through Pulse-Width Modulation, or PWM, for short.<\/p>\n\n\n\n

PWM is a technique used to control analog devices using a digital signal. Although a microcontroller\u2019s digital output can only ever be on or off (0 or 1), with PWM, we can mimic an analog signal. (It is worth mentioning that PWM is not a true analog signal.) PWM achieves this by rapidly switching the power state between on and off and thereby controlling the current.<\/p>\n\n\n\n
