RGBDigit Clock

A colorful 7-segment display for your data

RGBDigit Clock
What do you pick when you want to design “something” with a vintage or modern display? A clock of course! This is our first design with ’RGBDigits’ multi-color 7-segment display devices. With a BME280 breakout board (BoB) attached, the project will also cheerfully display temperature, humidity and air pressure. The clock is controlled by an ESP12 module, which enables synchronizing the clock with an Internet time server, change the clock settings from any mobile device or computer in the network, or transmit sensor data via Wi-Fi.
