In this article we are going to show you a simple LM386 audio amplifier circuit. Circuit diagram of the LM386 audio amplifier is shown in the given below diagram and animated picture. It is built by using popular amplifier LM386 {Read More}
For most systems single transistor amplifier does not provide sufficient gain or output impedance matching. The solution is only to combine multiple stages of amplification. In this amplifier circuit we are going to shows a simple two transistor amplifier. In {Read More}
An audio amplifier is a device that multiplies an applied input signal amplitude to a level that may be much higher than the input signal. The input is given in the form of audio or music. The amplifiers are classified {Read More}
Non-Contact Voltage Detector: Electricity can cause injury or even become the cause of death; that is why safety must come first when working with electrical devices or electricity. In this article, we will show you how to design a simple, {Read More}
In this 220 V blinking LED circuit, we powered a 3-volt DC LED directly with 220 V AC. This circuit can be used in special places to identify the main voltages. The capacitor is charged by a 470 k resistor {Read More}
This Electronic Mosquito Repellent Circuit is very easy and very simple. This circuit has minimum components repel mosquito. Large number of things like creams,coils, oils and other things are available in the market to repel mosquito. At the Same time all {Read More}
We generally worry about the wastage of water when we switch ON the motor and forget to turn it off. The Water Level Indicator employs a simple mechanism to detect and indicate the water level in an overhead tank or {Read More}
Resistor is an electrical component that regulates or limit the flow of electrical current in a electronic circuit. Resistors can also be used to provide a specific voltage to active a device such as a transistor. It is most commonly {Read More}
A DC to AC power converter is often needed at places where it is not possible to get an AC supply. A DC-to-AC power converter circuit is used to convert the DC power to AC power. In this article, we {Read More}
In this project, we are going to design a single-transistor FM transmitter circuit that works effectively in a 1-2 km range. In this circuit, we have used an electret condenser microphone as an input source that gains signal in {Read More}
