Big And Glowy Tetris Via Arduino
https://hackaday.com/2019/09/06/big-and-glowy-tetris-via-arduino/
Tetris was a breakout hit when it was released for the Nintendo Game Boy in 1989, in much the same way that Breakout was a breakout hit in arcades in 1976. Despite this, gamers of today expect a little more than a tiny monochrome LCD with severe motion blur problems. …read more (https://hackaday.com/2019/09/06/big-and-glowy-tetris-via-arduino/)
