Display Desired Alphabet on the MAX7219 8x8 LED Dot Matrix

STEP 1: The Circuit

The circuit is simple and can be built using the pin configuration;

VCC to 5V Pin of the Arduino Nano.

GND to GND of the Arduino Nano.

DIN to Digital Pin 13 of the Arduino Nano.

CS to Digital Pin 12 of the Arduino Nano.

CLK to Digital Pin 11 of the Arduino Nano.

STEP 2: The Code

The code for the project is available below.

Step 3: The Output

The desired alphabet that is typed in the serial monitor will be displayed on the 8x8 LED Matrix.
