Morning sir
okay aq sangat tertarik dengan artikel sirkuit ic tester ini,tapi teori
dan praktek sangatlah berbeda’aq pikir hanya beberapa ic yang boleh di
tes ‘yang lain mungkin tidak boleh ,gimana dengan pendapatku .

Hello,
Integrated circuits can fail because of internal shorts. I have seen chips smoke, explode, and melt plastic breadboards. I see that you do not protect the 8951 chips from high currents. Is this not necessary?
Thanks

sir
i like this idea and would like to implement it as my final year project.
i would be grateful if u can provide me following things..

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?
4]detailed circuit diagram and details abt the project.
5]PCB layout of the project.
6]how it tests the IC that is how it checks the IC.what is the logic ?
7]why to use 2 microcontrollers?

also if u have any links or other material which supports this poject .

thanking you in advance..!!

I have corrected the code but hardware does not working. It seems it require more component in circuit or design is incomplete. It is vsry sad to inform that we have selected this project for final year.all the documentaion is alraedy prepared but hardware does not work after many many consultation till today. And my daughter is going to submitte her project which is not working. It is vary sad that i have trust on this site and choose the project but it does not working. Code itself has very much error and hardware design is also incomlete. I have realy very much ashame that i have select this project from this site and played with the carreer of my daughter.
