Aim of this project is to determine characteristic of a NPN transistor by varying base voltage and detect Cut-off Region and Saturation Region.
We have used a potentio-meter for varying Base voltage. After assembling the circuit use a digital multi-meter and scale mark the voltage. You can also attach a multi-meter permanently.
This project uses IC LM35 as a sensor for detecting accurate centigrade temperature. We can activate or deactivate a device at a particular margin temperature. For simplicity we have used 2 LED for indication of both low (Green) and high (Red)Read More
The circuit illustrated here is used as Solar Cell. You can get plate from your old faulty solar calculator. Carefully dissemble plate with out tearing its 2 wire. Connect both wire to a LED through a switch. When Solar Plate is kept in sunlight and switched ON you will see LED glows .Read More
This circuits uses very few component and gives melody sound. It uses 3 terminal IC UM66 and can be build small enough to be placed inside a greeting card and operated off a single 3V flat button cell. There is not much to the...Read More
This circuit is used for playing MP3 files from a memory chip, card reader or from a pen drive. Same circuit is also used for receiving telecast of FM band Radio with digital Display of frequency. You will need MP3 Kit. Kit...Read More
Here is a simple Electronic Switch which can be operated by any Magnetic Field. With little modification It can serve purpose of REED Switch just by adding a Relay Module. It can not directly drive electrical loads since their...Read More
