realy nice project. but 'please' provide detail information about it.....

Please see this for detailed and complete circuit of digital clock with video.

realy nice project. but 'please' provide dip detail information about it.....

sir 

 i want make reverse digital clock so i want use down couter (or any other idea how to make it ) .

and to make it using CD4518 counter sir i need your help

 

share me more about digital clock project

The circuit is so badly drawn it's unreadable!

Can you redo it so I can decipher it

can you send me the complete schematic clear diagram please, thanks. here's my email lagazo_jake@yahoo.com

yes its a good work...

 

hello how its work myy timer cant work 

bari meharbani

 

 

Can you pls email me the circuit diagram at bushra.shk@gmail.com? I can't view it!

hi,please send me to  my email the complate projrct.

i can't read the  number on  ic in your paint

thanks.

mamadmamba@yahoo.com

can you send me the complete schematic clear diagram please, thanks

Sir ,please will u send me the complete project report within two days....please sir
nice

ITS A  VERY HELPFUL SITE FOR ME

Amazing! Sir, can you please send me a clearer copy of this schematic. Thanks...

the diode value ?

small signal diode 1n4148...

 

Please see this for detailed and complete circuit of digital clock with video.

please be careful if anyone is about to implement this circuit. The ic 74ls47 is used to  drive a common anode 7seg display and not a common cathode display. To find out whether you are having a common anode or cathode, please usse this link:http://www.engineersgarage.com/tutorials/seven-segment-testing

If what you have is a common cathode then you must buy the next version of 74lsxx ie, buy 74ls48 to drive a 7seg common cathode display. Anyway please verify before buying for i have not still tried it.

And i would like to know about the operation of the two diodes in the astable operation of the 555 timer...since i have seen only the use of one diode in forward biased condition from pin 7 to pin 2or 6 but here there are two diodes so i would like the help of someone.

can u plz send me detail of the diagram or proteus stimulation

 

good project

I login the web but it is still asking login in the The circuit is not downloading
I cant download it

sir please give me the detailed information on this circuit as i have seen that website of urs where u gave the full details but that circuit is too complicated so please share some simple circuit of digital clock as u have showed here(http://www.engineersgarage.com/node/4812?i=4058)
