Make a 7 Segment digital clock with MAX7219 and DS1307 Real Time Clock (RTC) - Quick and Easy!
A simple to build LED matrix flip clock.
Get coronavirus update of your country on MAX7219 LED modules with D1 mini (ESP8266) and MicroPython.
A very simple but useful device for your lab.
So far I was controling those matrixes with multiplexing. In this video I would use MAX7219 chip to do it
How to make 8 Digit Counter with 7Segment Display Module MAX7219 | MAX7219 based Counter with Eeprom
Hello today I will show you how to effectively control a MAX7219 with an ESP32 thanks to micropython
A fully integrated matrix LED display with microcontroller wi-fi connected and motion detector sensor.
This project is for making an audio (music) frequency spectrum analyzer / visualizer using Arduino, based on Shajeeb's Project.
Turn on all the LEDs using a 4x4 keypad with only constraint that the apart from selected LED its neighbors also flips its state.
