Build your own a cheap simple Microcontroller learning board S-52. The board is based on ATMEL’s new ISP chip AT89S51, AT89S52, or AT89S53. This board can be used by beginners for learning Assembly and C language programming. Single sided PCB file included.
Introduction
I have designed this leaning board to be used as a tool for learning [...]

ABSTRACT: In this modern, fast moving and insecure world, it is become a basic necessity to be aware of one’s safety. Maximum risks occur in situations wherein an employee travels for money transactions. Also the Company to which he belongs should be aware if there is some problem. What if the person traveling can be [...]

Unlike the IC testers available in the market today which are usually expensive, this IC tester is affordable and user-friendly. This IC tester is constructed using 8951 microcontroller along with a keyboard and a display unit. It can test digital ICs having a maximum of 24 pins.

The idea is whenever any engine observes a red signal on its track it will start decreasing its speed gradually and stops automatically at some distance from the signal pole. After then when it gets green signal the driver can manually start the train and go on.

Robotic Car is a miniature prototype car powered by batteries whose various movements can be control either manually or automatically, or the combination of both.

The present concept implements controlling of pump which pumps water from the sump (underground tank) to the overhead tank, using 8951 microcontroller.
The control panel, i.e. the main control unit of the system which consists of the primary control switches, pump indicator, siren and level indicators. The visual example of how switches And the indicators can [...]

Programmable number lock system is a high security number lock system that can be used to lock electronic devices. The present system is very user friendly. This system is a combination of software and hardware at its best. We have used a 8051 microcontroller kit for interfacing our system.

Hello friends, here is a clock project where CAT89C4051 is used as RTC. LCD is used for display. Using CGRAM area of LCD you cn create cistome characters. Here you will be able to see big and better digits in LCD. The digits are twice the size of the normal digits.
PCB design for project is [...]

Here is a project called ‘Digital Code Lock using AT89C2051′. LCD is used for display and a keyboard is used to input  the keys. This project source code is written in C. Both the C files and hex files are given for download.
A Brief Description:
This a simple project with efficient hacking prevention from Brute Force [...]
