From the project
This repo is an attempt at building a Pico based alarm clock. It was created for my kids and features:
This repo is an attempt at building a Pico based alarm clock. It was created for my kids and features:
- date/time (obviously) - alarm (plays wav file on sdcard) - weather (current and forecast) - epaper screen - 3d printable case
The configuration is done remotely, and the clock synchronize from time to time (it can be forced too). The time is also fetched from a remote server.
