Ping-Pong on AVR
In the next cleaning in the workshop I had a chance to stumble upon two 8x8 matrix indicators, Mega16 was found in the same place, buttons, layout. “What kind of programmer are you if Tetris has never written in his life?” The brain asked.
The end of the day was devoted to soldering this whole household with a canopy.
The scheme is as follows:
')
Unfortunately, Tetris’s hands have not yet reached, he warmed up by writing Ping-Pong.
Video of the device can be viewed here (video).
