Name of the circuit: LED Clock Circuit
There should have two sub circuits;
1- Controller Board
2- LED Board
Note: I will need to build different size of clock depending on the clients requirements, so LED board size may vary. But I should be able to use the same controller board for any sizes LED board.
The typical LED board sizes are 5" to 24" LEDs arranged as single line to double line as OO:OO:OO (Hr:Min:sec)
Controller can be PIC based and re programmable with small changes like OO:OO (Hour: Blink dots: Min)
