Introduction: Big 6 Digits Seven Segment Digital Clock

About: Innovator, Electronics evil.

This is a my second Digital Clock project.Which is having 5.5" height 6 digits seven segments.

Working with PIC16F876A microcontroller 
Power : 12V DC / Ampere : 1.2A Max 
Time Display : Hours / Minutes / Seconds  

Length : 24 inch
Height :  7inch

I will add a fully completed clock picture with aluminium frame which I made. :-)

Step 1: Find a Parts for Schematic Diagram

Check the attached circuit diagram for part list.

Common anode 7Segments - 6Pcs
PIC16F876A - 1
ULN2803 for Segment outputs driver stage.

2SA1680 and 2SC2785 for Segment Common Anode outputs.

check the pin outs for 7 Segment and finished circuit board.

Step 2: Aluminium Frame & Segments Fixing

Aluminum Frame made by Aluminium Box bars.


Step 3: Working Clock

    what is the use of uln2803 can't you light up each segment with simple resistor? what's the difference with uln2803?? thanks a bunch!

    why not you can use each transistor with resistor to drive segments. But the PCB will be more complex.

    kindly send me hex file on amnamrza901@gmail.com kindly i loved this project i want to make it for once

    Please provide me the hex file .

    Nice job! I'm interested in building your project to keep track of our triathlon times. How can I add tenths of a second to this?

    superr clock for my home plz send me hex file and circuits diagram I m very thankful to u. my email address gochcommk@gmail.com

    Thanks

    Hye.. currently i'm doing digital alarm clock with 5 time set. but it seem really complicated for the circuit. i need to use many decoder, latch and buffer. i dont know how to make it simple. before this i'm using Easy68k but now i want to try using PIC. can anyone help about the schematic first.. here is some document that can make u understand what i mean..
