sir ur projects are really of great help to student community
December 26th, 2008 at 12:46 pm
sir This project is very usefull to me.I want hex code for ur program.
January 9th, 2009 at 6:46 pm
sir,we would like to do digital ic tester as our mini project..but when both the programs are build using keil(simulation software) a lot of errors are seen and was unable to create the hex file.could you please correct the same and mail me.
January 18th, 2009 at 11:37 am
sir i am chethan studying in final year diploma we are doing the project that you have submitted on this website but we are not sure that it will work for every ic’s so can you tell me if it suit for all the ic’s & tell me the total cost required for this project………. please……..
January 20th, 2009 at 2:24 pm
Hi,
@keerthik
Pls let me know where exactly u r getting errors.
@chethan
I have written code to test only few gate Ic’s AND, OR, NOT, NAND
You can write code to test any Digital Ic’s.
January 24th, 2009 at 11:14 am
sir ur projects are really of great help to student and very usefull to me.I want hex code for ur program.
February 4th, 2009 at 8:10 pm
this site is very helpful to me to undestand how to use 8051 mc.
this is my mini project so I like this guidance.
please help me for how to use MC with LCD and latches.
thanking you.
February 27th, 2009 at 10:38 pm
hi sir,
i want to do same project but using pic 18f452 and i want to make use of memory card too .
basically i want to use memory card to store tests for all kinds of ICs.and while testing when we hit the number of ic using keypad. i want pic to search for that program in the memory card. if memory card had that program then it should send it to pic and pic will perform function to test ic. and then pic shall b able to display result on LCD.
could you tell me is that possible. i will be thankful to you if you can help me with this
March 18th, 2009 at 10:09 pm
Sir, i m doing this project as my mini project in 3rd year engineering. I wanted to ask u, is the circuit diagram u have provided full-proof or some other components need to be connected? If yes, kindly tell the connections. Plz reply as soon as possible. Thanks!!
March 18th, 2009 at 10:14 pm
Sir, also tell the modifications in the codes of master IC and slave IC while using Keil software.
March 24th, 2009 at 10:26 pm
I am a student of Electrical Engineering at Hawassa University in Ethiopia. I have studied and chosen this project as my final year project, I am keenly interested in it. sir I am stuck with the circuit diagram. What I need is the following:
1)Complete description on how we can interface keyboard and indicator to the 8951 microcontroller
2) Is this keyboard different from the keyboard of computer, if yes How can I design it?
3)You have said that this digital IC tester is used to test any ICs and to test a particular digital IC, one needs to insert the IC into the IC socket and enter the IC number using the keyboard and then press the “ENTER” key. The IC number gets displayed in the 7-segment display unit.Here, what part of the IC is tested? please, verify it for me.
4)Regarding to the above comments I wrote I need your response as early as possible (to mean your reply for what I have asked must be in a short period of time).
You can send me all the necessary information via my e-mail
my e-mail is:bayisahawa@yahoo.com
Thank you!

Please sir, can you kindly help me with the comprehensive assembly code for testing the logic Gates; NAND, AND, OR, NOR, and key-board interface with visual display for 8951 IC.
September 18th, 2009 at 6:02 pm
Hello. this is very interesting and clearly presented by you sir. Can u please mail the hex code to me.
thank you.
September 24th, 2009 at 5:15 pm
sir,
can u send me the circuit and programme code of the project digital ic tester…thanku sir…
October 5th, 2009 at 9:07 pm
Thanks for posting this! It gave me a clue how to parallel interface microcontrollers. I currently working on the same project but with a PIC micro.
Funny how most of the “graduating” students above dont even have a clue and are basically wanting to be spoon fed the answer.
Do some research and testing boys, that’s what engineers do.
Sorry for the rant.
Again, thanks for the valuable info, Sir!
October 6th, 2009 at 9:50 pm
please send me all details of this project
i want ko make this as my final year project
October 14th, 2009 at 9:53 pm
Interesting, I designed a fixture almost exactly like this in 1982 for a senior project.
October 19th, 2009 at 6:27 pm
Hi sir,
This is lavanya,i want assembly program for keypad and lcd interfacing to 89c51 microcontroller.if i press two keys at a time from keypad tha sting will be displayed in lcd.
Can any one give m the program for that,its very urgent for my project.plz give me reply anybody according to my requirement.
Thank you sir,

Good Project……….But what if the IC is not properly configured and what if it does not work before it is being tested.
An IC tester should be that whether it is in a working condition or not is also has to be tested …….prior to knowing that it is a particular IV like a NAND,NOR gate etc
