The requirement for greater voltage levels from low-voltage power sources is a frequent problem in current electronic applications. Devices can function properly even with low power supplies thanks to a voltage booster circuit, which raises the voltage. With the help of a PNP transistor 2N2907, an NPN transistor 2N2222, and a variety of passive parts […]

Simple Single Push Button ON OFF Relay Circuit
You may use a simple single push button ON/OFF relay circuit to operate a single push button device, such as a motor or light. Pressing the button causes the relay to flip between its on and off states. The condition can be reversed once again by pressing the button. Without the use of microcontrollers or […]
100 Watt Audio Amplifier Circuit using Transistors
The purpose of a 100 Watt Transistor Audio Amplifier Circuit is to transform a weak electrical signal from an audio source such as a phone or MP3 player into a considerably stronger signal that can power loudspeakers. In this circuit transistors play the vital role to amplify the input signal into a massive 100 watt […]
Simple Single Transistor Audio Amplifier Circuit
Just as the name implies, a simple single transistor audio amplifier circuit is a basic circuit that uses just one transistor to increase the amplitude of an audio stream. It is an excellent introduction to the principles of amplification and how transistors operate. Do you want to assemble a simple audio amplifier without a complicated […]
Simple Solar Garden Light Circuit using One Transistor
This solar garden light circuit uses just one special switch a transistor and the power of the sun to light up an LED at night. It works like magic when the sun goes down, the light automatically turns on and when the sun comes back up the light turns off. Circuit Working: Parts List: Category […]
PWM Motor Speed Control Circuit using Two Transistors
Resistors are helpful for many things, but they are not the best choice for changing motor speed smoothly. That is where a clever circuit with just two transistors comes in. This circuit acts like a fancy dimmer switch for your motor. By turning a knob called a potentiometer, you control the power going to the […]
