The MAX7219 LED driver can be used to control 7-segment displays up to 8 digits, bar-graph displays, or 64 individual LEDs. The driver communicates with the Arduino through SPI so you only need three wires to control the display. Since the MAX7219 can control a maximum of 64 LEDs, the ...

Interfacing MAX7219 LED Dot Matrix Display with Arduino When it comes to adding a display to your next project there are many options to choose from like OLED, 16x2 LCD, Seven Segment, and E-Paper Display. But there exists another type of display that I feel is mostly ignored due to...

Control Interface:Simple 4-pin interface with 5V/3.3V compatibility, ensuring versatile MCU control. Size and Weight:Compact 75mmx48mm module with a lightweight design, ideal fo...
In this video we examine the use of the popular MAX7219 for driving 8 digits of 7 segment displays or an 8x8 matrix of LEDs through the ESP32. We look at a C++ class that makes that task easier. https://www.youtube.com/watch?v=1qEirFJWScgFree book on ESP32 available here: https...
The brains of the operation is an Arduino Pro Mini. It controls two MAX7219s that drive the 42 LEDs plus the 7-segment display. A game like this is all in the code, and lucky for us, [Sunyecz22] made it available. We love how gorgeous the glossy 3D printed enclosure looks — betwe...
Have you tried running the matrix demo example in the project? Lost how exactly? The clock code from that blog is using the older version of the library, but it should be pretty simple to convert it to the new style if you look at the imports and how the device is initialised in the...
It connects the microprocessor with the 8 digit number of 7 digital LED displays, and can also connect to the bar graph display or 64 independent LED. It includes a B type BCD encoder on a chip, a multiple scan circuit, a segment drive, and a 8*8 static RAM used to stor...
