anwaralijamali16@gmail.com There is a list of touch switch circuits some are complicated and some are very simple. In this article we are going to build some simple touch switch circuits. We will use basic components( transistor and popular IC like 555 timer, 4011 CMOS, flip-flop IC). We can control our scandery circuits by using these touch … Read more
In this project we are going to built a simple IC 4440 amplifier circuit but the output is very nice and very high. It is 12 volts audio amplifier using is LM4440 IC 19 Watts amplifier. We have designed it without PCB and used few capacitors with it. we can use it in car audio … Read more
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 (IC). We have used 8-ohm speaker, one-watt speaker, four electrolyte capacitors. We have used 6 … 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 the single transistor amplifier circuit we have made a very simple amplifier with one transistor, … 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 into classes like class A, class B, class AB, class C, and class D. Here … 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, efficient non-contact voltage detector by using transistors. You can build this circuit by using simple components … 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 and diode. The capacitor is charged by a diode IN4007 and a 470k resistor. The … 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 these replant can become the cause of many diseases like skin cancer and etc. Creams … 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 any other water container. We have already posted a water level indicator and controller using … 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 used components in all types of electronics devices. Types of resistors There are two types … Read more
