This article is a practical work that requires less effort which you can try by yourself. It is a simple LED dimmer circuit using single Bipolar Junction Transistor (BJT). This is an interesting article especially for beginners in electronics which don’t have much idea on electronics or using transistors. Remember, transistor can be used as …
If a Diode is malfunctioning in a circuit especially in rectification circuit, then the whole circuit is faulty. Construct this simple diode tester circuit to help make your work easy. This project can also be useful for practical and educational consumption. It helps in illustrating how diode works for does that do not know how …
These chips are 8-pins packaged timers and can be operated by 2v to 16V. The NE555/ICM7555/ICL7555/TLC555 have the same pin out. They are all the same integrated circuits (IC) and have the same pins configurations. The difference between these integrated circuits is the manufacturer of the IC. NE555/ICM7555/ICL7555/TLC555 pin outs and functions of each pin …
These chips are 14-pins packaged dual timers and can be operated by 2V to about 16V. NE556/ICM7556/ICL7556/TLC556 all have the same pin out. They are all the same integrated circuits, they all have the same pin configurations. The difference between them is the manufacturer. Pin outs and functions of each pin below DISCHARGE 1_ Goes …
There are many different types of Capacitor. In general, they fall under one of these categories: Polarized Capacitor Non-Polarized Capacitor Variable Capacitor POLARIZED CAPACITORS Polarized capacitor types of capacitor must be connected correct way otherwise, will be damaged if connected wrongly. At least one of their leads (terminals) is mark either “+” or “−”. Examples …
In this post, you will learn how to calculate resistors in series and parallel. First of all, we shall be analyzing resistors’ networks that are in series connections and perform some calculations. After this, the analysis and calculations of resistors in parallel. RESISTORS IN SERIES Things you should know when resistors are connected in series. …

This post covers what is a diode, forward voltage drop and revers voltage of a diode. Also, it states the functions of diode as well as types of diodes. Testing diode also is not an exception. First of all, lets know what a diode is before the types of diodes. What is a Diode A …
To find the value of an unknown resistor in series connections using ONLY a voltmeter isn’t that hard! however, it might seems to be but, this post will put you through the easiest step by steps to do that. Example of a problem like this: Consider two Resistors in series connection; one has 1KΩ resistance …

This page covers Infrared Light Emitting Diode (IR LED) and Infrared Sensors types, applications and operations. First, let us know briefly what Infrared Light Emitting Diode (IR LED) and Infrared Sensors are then, their types, operations and applications. INFRARED LED (IR LED) This is a special LED that transmits infrared rays in the range of …
Capacitors also like resistors can be connected either in series, parallel, and or combinations of both. Their calculations are opposite to that of Resistors. That is; if they are in series, they will be treat as resistors in parallel and vice –versa. In this article, we will consider capacitors in series and parallel calculations. CAPACITORS …
