Mini Console with Arduino Nano https://youtu.be/IBdgpqdn1r4 In this project, we will create a small console using the Arduino Nano and an 8x8 LED matrix as our screen. The console consists of six fun and easy games that can be selected through a menu, controlled by a potentiometer and two small buttons. It's a simple and fun project to make, which will give you a glimpse into the world of Arduino and electronics. Materials: For this project, we will use: * Arduino nano * An 8x8 LED matrix with a Max7219 controller. * Mini proto-board. * Two small pushbuttons. * A 50k potentiometer. * A 3.7v 380mAh LiPo battery (or a 9V battery). * Various male-male and male-female jumpers. * An on/off switch. * Four M3x30 screws. Connections: We will start by connecting the LED matrix to our Arduino. Thanks to the Max7219 controller, the connections are quite simple. The pins where the connections should be made at the Arduino are as follows: * VCC - 5V * GND - GND * DIN - D12 * CS - D10 * CLK - D11 To connect the control, we need to follow the diagram drawn in the image. The right button is connected to digital pin 5 next to the left button on digital pin 4. The potentiometer is connected first to analog input A0, and then to IOREF (which will become the common power line), and finally the ground pin is connected directly to GND on the Arduino. The line on the proto-board where the ground pin is located will be the common ground line where the grounds of the buttons, potentiometer, and battery will also connect. To connect the battery, simply connect the positive side (red) to the power line next to the potentiometer, and the negative side (black) to the common ground line on the proto-board. The battery should be connected after uploading the code to the Arduino for safety reasons. NOTA: For greater safety, it is recommended to upload the code to the Arduino first before connecting the battery. The code used in this project contains six different games that can be selected through a menu. The games are: * Pong Classic: controlled by the potentiometer, with the goal of not letting the ball fall. * TedShow: a game where you must capture a line falling into a basket. Controlled by the potentiometer. * Space Invaders: controlled by the potentiometer and fired by either button. The objective is to destroy the enemies before they reach the bottom of the screen. * Snake: controlled by the buttons to turn, with points earned through circles on the screen, and lost if you collide with the edges of the screen or bite yourself. * Break Out: has as its goal eliminating obstacles using the ball on the screen and the potentiometer. * Racing: with the control of the potentiometer, the player must dodge various obstacles. Each game has a level system, which increases the difficulty of the game. This code is brought to you by user 3CarrotsOnAStick, who has this same project written in English, with some extra data on the game code. To upload the code, first install the LedControler and LinkedList libraries. Then, extract the ABHHGD file and open the .ino file with the same name. Project and text copied from this publication https://www.instructables.com/id/Mini-console-Con-Arduino-UNO/ I used an Arduino nano instead of an Arduino Uno, designed the casing buttons etc... to use more light with a 9v battery As we don't have the pin IOREF in the Arduino nano, we must connect it to the pin 3v.
