Diode is a semiconductor device having two electrodes. It is mainly made from Silicon or Germanium.
Diodes have polarity. A diode has two terminals, the positive terminal is called anode and the negative terminal is called cathode. These terminals can be identified as there is a circular ring on the cathode and the terminal without ring is anode.
We will try some exciting circuits in the coming blogs. The crucial skill of interpreting circuit diagrams cannot be ignored. Similar to preparing a food recipe, a crucial skill is to know the ingredients, proportion thereof and when to add in the making process as well as a power source to be low or high flame, microwave etc.[..]read more
Using soldering skills, here we are going to construct a simple musical bell using very basic components.
Material needed: card board/vinyl board or any other hard board
Speaker 8 ohm, IC UM 66, Transistor BC 548, Cell holder, 2 pencil cell.[..]read more
There are many creative pursuits of mankind which they achieve using their hands. Soldering is one of them. Soldering adds artistic element to the field of electronics. It is a skill that is developed over time by doing.[..]read more
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.[..]
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.[..]read more
A parallel circuit is an electrical circuit in which components are connected side by side. A parallel circuit has several branches. Current can flow from any of its paths.
If any component is not working properly or broken, it does not affect.[..]
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[..]
An Integrated circuit is also called IC, Microchip or Silicon chip. IC is basically a packaging of complex electronic circuits containing millions of components such as Resistor, Transistors and Capacitors etc. These electronic circuits are etched on a piece of specially designed silicon using a special [..]read more
In this note, we shall discuss the foundation for making any circuit, that is, PCB.
PCB is the base of any electronic circuit.
PCB is a thin insulating board made of fiberglass, composite epoxy, or other laminate [..]
Soldering firmly secures the components of an electronic unit. Here is the step by step guide to do soldering.Connect the soldering iron to the mains. It will take some time to get heated.
Insert the component at its position properly. Bend the lead of the components outward.[..]
We learnt about the importance of soldering in electronics in previous blog. Here, we are going to know about other material essential for soldering. Apart from soldering iron, other things needed for soldering are solder wire and flux.
Solder wire : Most common type of solder wire used in electronics[..]
