Since I started with arduino, i always wanted to make a game based on this platform. So one day I thought, why not create an old classic Tetris ? I remember to play it a lot in old times, mainly in windows 3.1 and 95 ages.
So, the first thing i needed to start the project, was to find out a RGB display, push buttons or a small joystick, and an enclosure to attach everything. After some research, I found out the Adafruit Neopixel Matrix 8×8, which is very easy to apply because it uses a just a single wire interface and simple handy library. So, I used two matrix of this, which gave me a display of 16 rows and 8 columns of RGB LED (or pixels). For powering, I used a Lithium Ion Battery of 3.7V 4400mAh. It was really necessary to put a capacitor (1000 µF, 6.3V or higher) across the positive and negative terminals of neopixel matrix.
The next step was to find out a way to control each tetris piece in the game….
Adafruit NeoPixel NeoMatrix 8×8 – 64 RGB LED Pixel Matrix: Put on your sunglasses before wiring up this LED matrix – 64 eye-blistering RGB LEDs adorn the NeoMatrix for a blast of configurable color. Arranged in an 8×8 matrix, each pixel is individually addressable. Only one microcontroller pin is required to control all the LEDs, and you get 24 bit color for each LED. (read more)
