Using only 2 capacitors, 3 resistors, 4 BIG seven-segment Display, 1 xtal, 2 switches ,and 1 Microcontroller PIC, you can build this Digital Led Clock main circuit.
you can use common anode or common cathode display, just select the display type. Here is the pinout information:(I have attach the all diagrams of parts and 7 segments)
I'm used 4x 6" big 7 segment display's.
Ok now everyone who need this kit buy over here:
Step 1: Simple Paper Copy Schematic
here is the schematic and part list for the project.
IC - PIC16F628 / PIC16F84A
