Proto-Tetris Machine

thingiverse

This is a rework of an old Arduino project. Basically, it's a set of pieces that works as a stand for a protoboard and some components that I've used to make a Tetris Machine. In the pictures, I'm using my DIY Controller but you can build your own using a PS2-like joystick and 3 buttons. Included the .ino file. It uses the Fastled, LedControl and Adafruit_TicoServo libraries (downloadable from the library manager of the IDE). Component list: <ul> <li>Arduino Uno/Nano</li> <li>Servo (a cheap SG90 is okay)</li> <li>Two 8x8 RGB Matrix (using cheap Chinese matrices found on eBay)</li> <li>Display MAX7219</li> <li>PS2-like joystick</li> <li>3 switch buttons</li> </ul> PINOUT for the Arduino: <ul> <li><strong>Joystick</strong></li> <li>AX --> A0</li> <li>AY --> A1</li> <li><strong>Buttons</strong></li> <li>Rotate CW --> D3</li> <li>Rotate CCW --> D4</li> <li>Start --> D5</li> <li><strong>RGBMatrix</strong> --> D8</li> <li><strong>Servo</strong>--> D9</li> <li><strong>Display Max7219</strong></li> <li>Data --> D10</li> <li>CS --> D11</li> <li>CLK --> D12</li> </ul> Important Tip: Don't feed the RGB Matrix through the Arduino, the two matrices together can consume more than 1Amp and your Arduino can't manage such high currents. There are two versions for the Matrix diffusor in one or two pieces. If you can manage filament changes I recommend printing the 'matrix_cover_with_diffusor.stl' and changing from white to a dark color fillament when starting to print the grid. The white panel has a 0.6mm thickness. You can also print the white panel and the grid separated then stick them with glue or tape but works better when printed in one piece. See below for some useful pics and more instructions/tips. See it in action (an earlier prototype) in this video: https://youtu.be/qHTFjGCErSI Enjoy this nice weekend project and have fun!!
