Arduino Tetris

gather the folowing items

item list:

1.arduino uno 2:OLED I2C SSD1306 3:AD Analog Keyboard Module or a replica created from a few resistors and 5 buttons 4: a few cables

first download the folowing file https://drive.google.com/file/d/1qkexPET5MUICAarGO...

in this file there are 2 size screens take the one that you have bought. and add the files adafruit_GFX and adafruit_SSD1306 to your libraries. after that run the exampel in the file where you got the libraries to test if the screen works(use the set up form the photo). if not look at https://www.adafruit.com/product/2719 or https://learn.adafruit.com/adafruit-gfx-graphics-l... for help.

once this proces is done you need to wire it all right up. you can keep the oled wired as is. and then use the set up in the picture. and if ur using a AD Analog Keyboard Module then wire it the same like the 3 cables coming from the button setup

us the code below and make sure u get al the lebraries installed it says it needs when you run it. and if you want help with creating shapes and other things use one of the previusly linked sites.
