“The starting idea for the project was to design a LED Matrix Alarm Clock that is made from off the shelf parts such as the MAX7219 - 4 in 1 LED Matrix, together with 3D Printed parts.
This clock would use a Wi-Fi capable chip such as an ESP32 in order to drive the LED Matrix as well as allowing the implementation of a variety of IOT related functions in the future.
Some concept functions are:
- Time tracking using NTP server from the internet.
- MQTT Integration
- Alarm clock.
- Node-RED Integration.”
