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
By combination of NAND Gate we can construct AND, OR, NOT (basic logic gates) so we call NAND as Universal Gate. This is also true for NOR Gate. But we prefer NAND gate over NOR because of low logic effort and delay. For input...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
