سون سگمنت 7SEGMENT 8 DIGIT FOR ARDUINO:
MAX7219 digital display control module.
This module is compatible with 5V and 3.3V microcontrollers.
You can use it for Arduino.
MAX7219 is an integrated serial input/output common-cathode display driver, connecting your microprocessor to a 7-segment, 8-digit digital LED display.
Only three IO ports are used to drive the eight-digit display.
MAX7219 supports both flicker-free and cascading displays.
Wiring instructions (for example, it can connect any IO port, changed the port definition in the program):
VCC and GND must not be connected in reverse, so as not to burn the chip
Material: PCB + Electronic Components
Dimension: 82*15*12mm (L*W*H)
Shell Color: Blue and Black

MAX7219 is an IC that is used to drive 7-segment LEDs (up to 8 digits), block displays (bar displays), and 64 individual LEDs that are comon cathodes. To communicate with a microcontroller, MAX7219 uses the SPI communication system. So to drive 64 LEDs only need 3 ports of the microcontroller.
In this article I will show you how to use a 7-Segement module that uses IC MAX7219 as the driver.
In this tutorial I use Arduino Nano board. If you have never used it. I suggest reading my previous article about “How to Use Arduino Nano“.
