A power amplifier circuit is the one with minimum output impedance, used to drive loads like a speaker, which require high power at low impedance.

This circuit will help you to guard your precious documents as well as jewellery from intruders or theft. All you need is just to place

In early years of computing, processor has to wait for the signal for processing. So processor has to check each and every hardware and software

Here is a simple project more useful in watering plants automatically without any human interference. We may call it as Automatic plant irrigation system. We

The battery is charged with small amount of AC voltage or DC voltage. So if you want to charge your battery with AC source then

Consider a task of moving a charge from A to B in a uniform electric field. Let this movement be against to the electric field.

In olden days while we were using analog signal for communication, the jamming circuit was very easy just by producing the high frequency noise signals,

In this session we will see how to interface 16×2 LCD to PIC18F4550 microcontroller which is of family PIC18F. You can get information of 16×2

A power amplifier circuit using MOSFET has been designed to produce 100W output to drive a load of about 8 Ohms. The power amplifier circuit

Password Based Door Lock System using 8051 Microcontroller is a simple project where a secure password will act as a door unlocking system. Traditional lock
