Big 7-segment Digital Clock

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.

Step 1 Simple paper copy schematic

here is the schematic and part list for the project.

IC - PIC16F628 / PIC16F84A

Have you .hex File for PIC16F628

[slwthr]

Sorry!I heven't

[ramesh77]

Hi im interested on this very much.....can you please send me the circuit diagram and the .hex file if using PIC16F628A??

[e-mail]

[slwthr]

I don't have one for 16F628A..got one with 16f876

[dansan101]

Hi, im looking at replication this and i was wondering if you could tell me where you got the 7 segment displays, and if you could send me any of the relative informtion on the circuit. Cheers dan

And sent the mail with new design!

Can you send the list of the entire parts and entire circuit diagram to email below.
I only have 4 pcs. of 3 inch displays, will the clock work if I use them instead of the bigger displays.

Hi, can u please send me the ciruict schematics and help me about how to connect the 7 segment displays to my microcontroller? I am using Bare_Bones Board as my microcontroller and was trying to use 74hc595 bcd, but my clock doesn't work.... Could u please help me

[slwthr]

Dear friend,I haven't try any microcontroller circuit using "Bare-Bones Board"..I only used PIC microcontroller and assembly or C compile software's. But Bare-Bones Board has a Atmel chip and its own software nah.

Why your clock not working? what trouble you guess? what schematic you want?

[Shabbar]

WOW =D

[ecinev]

hey..what about the hex code

[slwthr]

Cool :)

[ecinev]

hey.. we're asked to built the same circuit in the josepino.. i tried your hex but it doesn't fit. .... Do you have the hex for it??? 2 capacitors, 7segment anodes, 10k resistor, pic16f84a, 2 switch... can you help me?? please...

[slwthr]

which display size u used? Big 7 segments or small one? Microcontroller Circuit is just simple like this.(From Josepino) but If you are using Big 7 Segment you must have to build Transistor array(darlington) like this diagrams.then couple with microntroller out puts to Big 7 segment display's.

Does your 7 segments displays any thing??

[cali909]

Hey wass up brother, man! that is a great digital 7 segment clock. I am interested after taking my first intro. class of engineering and about to complete my programming class. Arduino can I have a copy of you schematic and programming layouts to apply practice in my field.

[e-mail]

[ecinev]

small one...but the display is incorrect..

[slwthr]

please give me your email address,will massage you this clock modified version without transistors.(with darlington array IC control)

[slwthr]

u mean hex for this clock?? I have sent email yesterday,and find the attached zip file of Big Clock schematics and hex code). (from my hotmail : [e-mail]) so what diagram you want???

[ecinev]

i'm trying your hex for this diagram...just this diagram....

[ecinev]

i'm trying your hex for this diagram....just this diagram

[ecinev]

sorry for late thank you's...thanks again for helping me.. problem solved?!
hope you can help others as well.. :)

[sponcio]

hi sir! can you pls help me to do a 7 segment clock (the small one like a match box) i just need the seconds .. what IC and schematic diagram will I going to use ??

[vasanthsam22]

hi bro i'm doing my 3rd yr ece but doesnt knw the basics but i like to do this clock so plz help me bro give me guidance and sent all the info of this clock to me
plz.....
