Introduction: Big 6 Digits Seven Segment Digital Clock

Picture of Big 6 Digits Seven Segment Digital Clock

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

Picture of 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

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!

slwthr (author)nodoubtman2014-01-07

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

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

smorad (author)2012-05-02

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..

chiren1 (author)2012-03-23

where is the hex file

solangi01 (author)2012-03-13

I like this clock I make for my home plz send me hex file and complete and clear circuits diagram I m very thankful to u. my email address solangi01@yahoo.com

Do you have a modified setup for just hours and minutes without the seconds panels?

nice one user:slwthr
but i recommend a clean desk atleast when taking the picture :P
plus(+)
scan the diagrams will ya :P

possible to read though!
