Electronic Clock for Raspberry Pi Pico

The Electronic Clock for Raspberry Pi Pico is an LED digit electronic clock project designed for the Raspberry Pi Pico!

It incorporates a high-precision Real-time Clock (RTC) chip, photosensor, buzzer and buttons, and features multiple functions including an accurate electronic clock, temperature display, auto-brightness adjustment, alarm and custom button configuration.

Open-source code and development tutorials are provided to help you get started and make your very own original electronic clock! The USB connection provides both power and a debugging interface for programming.

Not compatible with the Pico W (the taller debug header gets in the way!).

A Raspberry Pi Pico is not included - click here if you'd like to buy one. Your Pico will need to have male headers soldered to it with the pins pointing downwards (or grab one of our pre-soldered Picos).

Note: Some simple assembly required.
