Single Tune Musical Bell

In this article, we shall learn to make a musical bell. For this, we shall only use three basic electronic components.
These components are:
(i) IC UM 66;
(ii) Transistor BC 548;
and (iii) Speaker.[..]

LED Display

In this activity, we are joining LEDs in parallel connection by soldering to make an interesting display. Parallel connection means the positive terminal of all the LEDs will be joined together and all the negative terminals will also be joined together with the help of soldering using connecting wire.[..]

Series Circuit : A continuous chain/ Hum Sath Sath Hain

In an electrical circuit, there are basic two ways in which components can be connected. One way is series connection.
In series connection, all the components are joined to each other like a chain in a single line style.
Current just has one path to flow from. Current flows from the source[..]

Light Dependent Resistor (LDR)

LDR is a special kind of resistance, which varies according to the light falling on it.

An LDR is a kind of light sensor and is also called photoresistor. It is made up of photo resistive material Cadmium Sulphide.
LDR’s resistance varies [..]
