All time great & latest updates!

This is 8051 code to create inbuilt “delay” function. In Keil, there is no inbuilt function for delay. So we have to use the “for” loop to create delay, every time. So study this program so that you will understand how to create UDF only once in your program, and just write delay(1000); or something Read More

Everything for robotics students

This page presents everything for robotics students. The regularly needed software, files, programs, codes, hardware details, latest updates, etc. This page is divided into two sections: For Basic Batch Students i.e. Level-2 and for Advanced Batch Students i.e. Level-3 students. Interested to join our robotics courses? Take online admission.   For Level-2 Students For Level-3 Read More

This post gives the complete details of 10th standard & 12th standard Board results of Amravati Board, Amravati. You can also refer to the guidelines of Akola online admission process to be launched this year in Akola. Please note that the official results dates of SSC is declared as 6th June, 2017 and that for Read More

This is a special application of IC555 clap switch with timer mini project. It uses a condenser mic to pickup the clap like sharp sound and trigger the IC 555 designed as monostable multivibrator, as shown in the following circuit. Working of the circuit The circuit uses one condenser mic to receive the clapping sound and Read More

This is a very interesting IC 555 soft touch switch door lock mini project. It is very easy to construct and useful for your school or college level mini project submission. The actual size PCB layout of the project is also given here, so that you will be able to construct it within an hour if Read More

Animated working of bridge rectifier circuit

Why am I publishing this animated working of bridge rectifier circuit? Because in my long teaching experience, I have noticed that sometimes, the 11-12th standard students get confused with the working of bridge rectifier and cannot properly explain it. This same case occurs for HWR & FWR circuits as well. So I have created the animations of all these three Read More

Why I am publishing this animated working of full wave rectifier circuit? Because in my long teaching experience, I have noticed that sometimes, the 11-12th standard students get confused with its working and cannot properly explain it. This same case occurs for HWR and BR, as well, which are also explained. So just watch the video given Read More

Why I am publishing this animated working of half wave rectifier circuit? Because in my long teaching experience, I have noticed that sometimes, the 11-12th standard students get confused with its working and cannot properly explain it. This same case occurs for FWR and BR, as well, which are also explained. So just watch the Read More

This is another circuit of IC 555 infrared burglar alarm project. It is very simple to construct and submit it as a mini project for your school and college level project submission. The basic idea of the circuit is almost same used in the previous circuit of IC 555 simple burglar alarm, only the wire loop Read More

This is another circuit of IC 555 simple burglar alarm mini project. It has been fully tested in our lab and its PCB layout is also given below. The circuit uses the simple trick that whenever, pin-4 i.e. the RESET pin of IC 555 is grounded, all its functions stop. But when it is raised to Read More
