We get a lot of calls/emails from Engineering students asking for help in Frequently Asked Questions in Project Viva.
So Team Microtronics have come up with the FAQs for Electronics projects.
Below is the list questions asked in Project orals. These are FAQs for 8051 based Microcontroller projects.
Go through the wide range of Frequently Asked Question in EXAM given below. Read the Frequently Asked Questions for 8051 exam questions.
