transistor

Transistors are made up of semiconductor material which is most commonly used for amplification or switching purpose, although they can also be used for controlling the flow of voltage and current. Not all but most of the electronic devices contain one or more types of transistors. Some of the transistors placed individually or else generally in integrated circuits…

555 time IC is very powerful and versatile IC, it can be used in many forms. In this tutorial we are going to see how a 555 IC can be used as Audio Amplifier. A low power audio signal can be amplified using 555 Timer IC.

This circuit is divided into two parts: part one is Preamplifier circuit, which consist a BC547…

Clap switch is an interesting hobby circuit that turns on the lights with a clap sound. Although its name is “Clap switch”, it can be turned ON by any sound of approximately the same pitch as a clap. The main component of this clap switch circuit is the Electric Condenser Mic, which has been used as a sound sensor. The Condenser Mic basically converts sound energy into…

Water tank overflow is a common problem which leads to the wastage of water. Though there are many solutions, like ball valves which automatically stop water flow once the tank gets full, electronics enthusiasts prefer smart electronic solutions. This comprehensive water level indicator project tutorial will guide you to build a simple DIY water level indicator circuit that…

In electronics most commonly failed component is transistor. To test the working of the transistor, one must go through a lot of testing though multimeter. By testing one terminal after another, this consumes a lot of time and also this option is no good for newbies. The transistor testing circuits which are present already are complex to understand and design. In this…
