This is an 8x8 RGB LED module, being driven by 4 x 74HC595N Shift Registers controlled by a Boarduino (Arduino clone that can be used on a breadboard). The time data is from a DS1307 Real Time Clock IC.
The display is outputting the time and then the date and cycling through 7 different colours. This took me about 5 hours in total to put together and code.
This is really a test for another clock project I have in mind.
