Planning to make your own digital clock that also displays a game of pong on it?
This project uses the classic video game to tell the tim, the players can win or lose and their scores will reflect the hours and minutes. This project uses a 24 x 16 LED matrix driven by an Arduino board with 3 shift registers to control the columns, buttons that allow to set and change time and a 4017 decade counter IC with 6 transistors for scanning the rows.
This dual functioning gadget is quite useful as it can do two things at same time. You can also use it as an alarm clock which is also very efficient.
