arduino-led-matrix-clock 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.

Behind the clock is an Arduino driving a MAX7219 LED controller. Using the MAX7219 was a challenge because it expects a grid of LEDs while the clock needs a linear array.

The display uses two MAX7219 LED drivers to control the grid which is build on a big hunk of protoboard. An Arduino ties the whole system together with a Chonodot for accurate time keeping.

In this step-by-step tutorial, we're diving into the world of electronics and microcontrollers to create a personalized 8 by 8 LED matrix that can be controlled using an Arduino board ...

The MAX7219 driver simplifies the process of controlling multiple LEDs in matrix or numeric display form. For fast prototyping, software code developed for the MAXREFDES99# reference design works with ...

It consists of only a few components: - Arduino nano microcontroller - 8 by 8 matrix module with MAX7219 driver - DS3231 realtime clock module - and one Button By the way, I used the box from one of ...

Project uses an Internet-connected ESP32, a 4-unit MAX7219 32x8 LED module, and multiple DHT11/22 sensors for inside/outside temperature and humidity. This hardware/software combination implements a ...
