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
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
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 very simple circuit to control a speed of a DC motor according to the room temperature. It uses LM35 as heat sensor. Very few component is used in this project.
