The black chip as you can see in the picture is the MAX7219. The only difference is that instead of the DIN its Dout. Similarly, on the output side, we have the same number of Pins with the same names and in the same order. The Black one is the Ground and the 5 th one which is the red is the VCC 5 volts. The green one is the clock, the yellow one is the CS “ Load Pulse “. I would appreciate your support in this way! I may make a commission if you buy the components through these links. The components that we will need for this project are Without any further delay let’s get started! The Bluetooth module used in this project is HC-05 but if you want you can also use HC-06 Bluetooth module. This 8×8 moving display system will be controlled using the android cell phone application. In this tutorial, you will learn how to make your 8×8 led matrix moving display system using Max7219, Arduino Uno or Mega and HC-05 Bluetooth Module.
