Alright Waqar. What do you need.

Start with the blocks.

Display - use Max 7221 or 7219.

Keyboard (for setting clock) - take them into a port, if you use 4 buttons, you have enough left over for the display driver.

Output ? A tone first like in the other thread here, then add the fancy westminster chimes. Haven't found the chip yet though.

Powersupply, crystal, reset generator.

Software: Driver for Max 7219: SPI bus.
Clock timer: Use Peter's stuff, in the link I pointed out.


Get the BITS working, get the display to count up when you press a button, down when you press another.

Get the clock working. Pulse pins at 1 Hz, 1/60th Hz etc.

Putting that lot together should keep you busy....
