You you can use it for Arduino. CLK--clock signal feet. Digital tube 8 grey level is adjustable. Display device is 4bitWhite word common anode tube.
Arduino Clock wiring - Castells
In this project we are going to design an 8x8 LED matrix display, for that we are going to interface an 8x8 LED matrix module with Arduino Uno. An 8x8 LED matrix contains 64 LEDs which are arranged in the form of a matrix, hence the name LED matrix. News (data receiving pin), CLOCK (clock pin), and CHIPSELECT (command receiving pin).

Arduino Digital WIFI LED Dot Matrix Clock ESP8266 MAX7219
1/1/2015MAX7219 and 8 x 7 Segment LED Display . but I wanted to be able to send data over a Serial connection. The MAX7219 presents some problems in sending a string of characters, unlike some other drivers like the TM1638 where a string can be sent, the MAX7219 needs to set each LED individually. Data In is connected Arduino pin 12
How to connect LED Matrix into Arduino using MAX 7219
Arduino LED Matrix Clock: This clock uses five MAX7219 8x8 LED matrices to display a clock. The two left units display the hour, the right two the minutes, and the middle matrix counts off the seconds. This is accomplished by illuminating one LED per second, counting acros. . .

Arduino 8x8 LED Matrix Tutorial with Circuit Diagram Code
Finally, the MAX7219 serial in, load and clock pins will go to Arduino digital pins which are specified in the sketch. We’ll get to that in the moment, but before that let’s return to the matrix modules.
