Our project is infact an Arduino with Serially Interfaced MAX7219 Operates an 8X8 LED Matrix to display a heart pattern. The MAX7219 IC is a serial input/output common-cathode display driver that ...

A clock based on 4 8x8 LED matrix modules with MAX7219, is controlled by an Arduino Pro Mini 3.3v, and includes a DS18B20 digital temperature sensor - arduino_led_matrix_clock/README.md at main · ...

A retro style clock with matrix LED display using an ESP32 microcontroller with automatic NTP time sync. Open the project in PlatformIO. Wait for PIO to configure and download the required libraries: ...

For the most part, the build is what you would expect: a 16×8 LED Matrix display driven by a TLC5920 LED driver, with an Arduino that uses a DS1307 RTC (real-time clock) with a coin cell battery ...

Making a clock with a common microcontroller like an Arduino isn’t very difficult. However, if you’ve tried it, you probably discovered that keeping track of wall time is difficult with… ...

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...
