Doctor's Diary

         This is the model software from electrofriends.com. We successfully implemented the need and necessary concepts of a doctor, for his stand alone clinic. We hope this software package will definitely help the students, to get an idea about their academic projects. The most emerging technology, J2EE(JSP), SQL, JavaScript are the backbone of this project. A student can get these codes and can find how the real time practical needs are made.  Read more...

Digital IC Tester

             An Integrated Circuit tester (IC tester) is used to test Integrated Circuits (ICs). This IC tester is constructed using 8951 microcontroller along with a keyboard and a display unit. Since it is programmable, any number of ICs can be tested within the constraint of the memory available. This IC tester can be used to test a wide variety of ICs which includes simple logic gates and also sequential and combinational ICs like flip-flops, counters, shift registers etc. It is portable and easy to use.  Read more...

Dc motor control using IR data communication

Current generation moves into wireless technology. Every one wishes to use remote controls. In this way, the speed of the DC motor is controlled by IR rays. IR rays get modulated with combination of data signal and carrier wave of 38 kHz. At the received end, the modulated signal is demodulated which is given to another controller, connected to the Dc motor driving circuit

Intelligent Train Engines

             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. In the mean time when train has not stopped yet and a red signal becomes green then it crosses the signal pole with low speed and then driver can slowly increase the speed.    Read more...

Robotic Car

              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. Here the command is given through keyboard; it would have been better if we used IR remote control or something of that kind rather than using keyboard for commanding. However, by realizing the complexities we have made simple using keyboard. Read more...

Programmable number lock system

     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.  Read more...
