LED  Display

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...
Parallel Circuit: current flowing side by side

Parallel Circuit: current flowing side by side

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 the flow of current. In...

Printed Circuit Board (‘PCB’): A Solid Foundation

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 material. It has conductive lines and pads that are...
