Final Project

This project uses a joystick that creates a small animation on the LED matrix.

Components

To set up the project you need:

• 1 x Arduino
• 2 x Breadboard
• 1 x Joystick
• 1 x LED matrix
• 29 x Wires

Joystick

Joysticks often occur this way, with a round upper part to use it and five legs that represent anode, cathode, input pin to read the signal and the entries that read the horizontal and vertical coordinates. To set this up this element libraries are not required, but the lines of code below must be written.

In this way we set the input pins and the coordinate pins. So in the setup method you set the input pin as an input and activate it.

So to verify the operation you can use a method like getDir() that takes the position of the joystick to print it at the terminal and store it into a variable. At first ou read the entries, then find the interval for each joystick position by reading the output of x and y, finally you can find each joystick position and test the operation by printing the result in the terminal.

Matrice di LED

LED matrices work on the basis of rows and columns, in fact the output pins are 16. The image explains well how the pins are attached, so the rows represent the GND, while the columns the positive pole. To turn on the whole matrix, attack correctly the pins and give GND to the lines and + 5V to the columns.

In the code of the image the central columns light up.
