In this instructable, I am going to show how to use an LED Matrix by Arduino. Following the step carefully, and you will make it successfully!

Arduino Leonardo

breadboard

5V power supply

8x8 LED matrix with MAX7219

head wires

Button

Electrical conductance (electronic color code: white brown orange black brown brown)

• Matrix-breadboard(picture 1)

Max7219 CLK => Arduino digital pin10

Max7219 CS => Arduino digital pin9

Max721 DIN => Arduino digital pin8

Max721 GND => Arduino digital GND

Max721UCC => 5v

• Button-breadboard(picture 2)

Pin 1 => 5v

Pin 2 => conductance(the other pin connects to GND) and Arduino digital pin2

• Final circuit(picture 3)

The function of this code is when you press down the button, the LED matrix will appear in the shape of a heart. Changing the code can help you generate different patterns on the Matrix. In the following pictures, you will learn how to change the code on shaping shapes.

Can you think of any use of this instructable? I think it’s a good tool when you are making a birthday gift to your love. In the following pictures, you will find out how to make it.

Prepare a box and make 2 holes. (one for matrix, another for button) (Picture 1 and 2)

Decorate your box! (Picture 3)

Choose a nice gift and give it to your love!
