Voice broadcast RTC based on Raspberry Pi pico

Overview

# Design of voice broadcast rtc
! [actual picture]

In short, this is a small electronic production that can tell time by voice. We all need to know the time in our daily life. And sometimes we don't want to, or can't see the time, but want to hear the time. That's what this project is about.
(Actually, I made up all the above. It was a physical work mixed with the university's professional design course)

The Raspberry Pi Pico development board is used as the controller, and the YF017 series voice chip is used as the audio output. It is a OTP voice standard chip with PWM output, which can directly drive the speaker. A total of only 3 IO ports are needed to control it to send out corresponding PWM voice signals, and the working voltage is 2.2-6V. One or two pieces.
The address and corresponding content of the voice chip are in the document
