An LED-matrix clock made with Arduino, using a DS3231 RTC module and four MAX7219 LED-matrix controllers. It also has an ambient light sensor for controlling the brightness.

Scrolling Clock - Arduino UNO, RTC, and DHT-11 Hey Science Enthusiasts! Get ready to dive into the world of Arduino with a fantastic project: a 64x8 LED Dot Matrix Clock with temperature and humidity ...

An image of a dot matrix display is shown below. MAX7219 Chip 8-Digit LED Display Driver The MAX7219 chip is a serial input/output common-cathode display drivers IC that can interface microprocessor ...

The DS3231 RTC module is the most accurate and reliable real-time clock module to use in your Arduino projects. Unlike low-end timekeeping ICs found in basic timekeeping devices, the Arduino real time ...

This simple but fun project shouldn’t put too big of a dent in your parts box, since it’s essentially an Arduino, a real-time clock module, and a 32×8 LED matrix to display the text. We love ...

Utilizing a previously ordered PCB stencil and following the same LED arrangement, I assembled the matrices. Soldering the MAX7219 integrated circuit and male mezzanine connectors completed the ...

LED Matrix Clock / Weather Forecaster Project uses an Internet-connected ESP32, a 4-unit MAX7219 32x8 LED module, and multiple DHT11/22 sensors for inside/outside temperature and humidity.

Not that we’re complaining, of course. The latest entry into the pantheon of unusual timepieces is this ESP32-powered desk clock from [Alejandro Wurts] that features a folding LED matrix display.
