LED 8x8 Dot Matrix using Arduino This project demonstrates how to control an 8x8 LED dot matrix display using an Arduino and the LedControl library. The code initializes the matrix, displays a ...

The master Arduino handles the LCD display and temperature monitoring using a DHT22 sensor. The slave Arduino manages the Snake game displayed on a 16×16 dot matrix display, controlled through an ...

The frame for the Arduino dot-matrix printer was created using the fantastic Autodesk Fusion 360 application which is free to download and install.

Using an Arduino library (MD_MAX72xx.h), I uploaded a test code to verify the hardware. The LEDs lit up beautifully, displaying coded animations flawlessly, confirming the success of the circuit.
