Driving an 8×8 (64) LED Matrix with MAX7219 (or MAX7221) and Arduino Uno
https://www.electronics-lab.com/driving-8x8-64-led-matrix-max7219-max7221-arduino-uno/
Hi guys, today we will be focusing on displaying mini graphics and texts on an 8×8 LED matrix using the MAX7219 (or MAX7221) LED driver and the Arduino Uno. The 8×8 LED matrix displays are usually used for the display of symbols, simple graphics and texts. Made of super bright LEDs, they produce low resolution […]

jollifactory @ instructables.com has published a large 8×8 LED Matrix Display which is driven by a MAX7219 and Arduino. For this project, we will be building a single color large LED matrix display which is made up of a few large 8×8 LED matrix modules daisy-chained together. Each of these 8×8 LED matrix modules is around […]
IP Time Clock using NTP protocol
https://www.electronics-lab.com/ip-time-clock-using-ntp-protocol/
by msuzuki777 @ www.instructables.com So this Lazy Old Geek (LOG) has a couple of clocks in my bedroom. One of them loses time when the power is lost. The other is semi smart and automatically adjusts for Daylight Savings Time. Unfortunately, it does this using the old standard so I have to re-set the time four […]
