MAX7219 8-Digit 7-Segment LED Display Module For Arduino

On which includes a B-type BCD encoder chip, multi-channel scanning loop, segment the word drive, but also an 8 * 8 static RAM for storing each data. Size: 82 * 15 * 18mm Color: Red Note: VCC and GND Do not reversed, it would burn the chip. 51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines GND is connected to the GND pin Pin 12 is connected to the DIN pin Pin 11 is connected to the CLK pin Pin 10 is connected to the CS pin Wiring instructions (a program, for example, you can pick any IO port definition can be modified in the program): VCC: 5V GND: GND DIN: P00 CS: P01 CLK: P02 MAX7219 EWG 8-Digit Digital Tube Package Included: 5 X MAX7219 Module 5 X 5P Straight Pin 5 X 5P Bent Pin What is going on in this situation? If all five are not working or all display is incomplete, then there may be a code error, you can con tact us to get the correct code or tutorial. Finally: This requires the Led Control library to be installed – https(:)//github(dot)com/wayoda/LedControl Tutorial Links: https(:)//www(dot)hackster(dot)io/mitov/7-segment-display-clock-with-max7219-and-ds1307-rtc-a028b9 https(:)//circuits4you(dot)com/2016/05/19/max7219-segment-display-arduino/ Integrated Driver: Features the MAX7219, an integrated serial I/O common-cathode display driver Versatile Compatibility: Compatible with Arduino, 51/AVR/STM32, Raspberry Pi, ESP8266, and Nodemcu Easy Wiring: Requires only three IO ports to drive the eight-digit display, with clear wiring instructions
