Learn to Re-use your thrown Tube Light using simple electronics circuit. This circuit will extend tube light life to one year more.
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.
Learn how number of turns in a transformer winding effects emf. Good experiment for class 12 CBSE. Input AC voltage to primary is 220V
This is Simple Circuit to make a Traffic Light using popular IC 555. A fixed interwell of square wave is produced by 555 IC which is fed to a Counter IC CD4017.
We can protect our product or thing by making them touch proof or we can stop any unidentified persons entry in our house by making door and window touch proof. This circuit alert us when anyone come to stole products from our house or touch any metallic thing at door / window or in side
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)
Here is a Simple Temperature Display Circuit using LCD (Liquid Crystal Display). For Heat Sensor we have used IC LM35 (Precision Centigrade Temperature Sensors) whose Output voltage is linearly proportional to the Celsius (Centigrade) temperature.
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 .
Rectifier is a good project for electronics beginners. Ideal project for Class 12 CBSE School. A rectifier converts AC (Alternating Current) in to DC (Direct Current)
Here is an interesting electronics project to detect if there is raining or not. Same circuit can also be used as water level indicator or as a tank overflow indicator.
Learn to make a NOR gate using Basic Electronics Parts such as Diode, Transistor etc.
Learn to make a NAND Logic Gate using Basic Electronics Parts, Ideal Project for Class 12 School.
