What is an Electronic Circuit Project?
An electronic project is basically a circuit project built using a handful of passive and active electronic parts, by soldering them on a printed circuit broad or PCB.
The passive components are those components which do not have semiconductor material inside them such as resistors, capacitors, inductors, etc. These are called passive components because these components are not able to actively work with electricity or electrons.
On the other hand active components are those components which are internally built using semiconductor material. These components include all types of diodes, transistors, and integrated circuits.
These are called active components because the semiconductor material inside these components are able to actively work with electricity or electrons. For example diodes can rectify an AC, transistor can amplify current and voltage, whereas ICs can do similar tasks which are even more complex.
Some of the best electronic circuit projects you can learn from this website are provided below:
