Every electronic circuit works under two electrical quantities, current and voltage and it is not possible to detect voltage and current with our naked eye. This tutorial is for beginners who are new to electronics. […]
Electronic systems are built around analog and digital components. They comprise resistors, capacitors, diodes, inductor, operational amplifiers and transistors. These components are often called active and passive elements. Majority of the analog circuits consist passive […]
Resistor, this is a common electronic component seen in electronic circuits. This is one of the basic components used in Emergency lighting, Medical Devices, Battery operated equipment, and many more applications. The word Resistor came […]
Most modern wireless experimenter kits comes as modules that just plug together rather than individual components. Electronic newbies, practicing engineers, and experienced hands alike are sure to find that these inexpensive modules interesting. Recently I […]
The circuit below shows a simple light emitting diode tester, powered from a 9V compact battery,which can be used to test almost all common light emitting diodes (LEDs). Common LEDs require a dc forward bias […]
UART (Universal Asynchronous Transmitter Receiver), this is the most common protocol used for full-duplex serial communication. It is a single LSI (large-scale integration) chip designed to perform asynchronous communication. This device sends and receives data […]
Solar electronic snake repellent presented here is a proven solution to keep all poisonous snakes out of dog kennels, stables, etc. All you need is to simply place the device on the ground to remove […]
Here is one interesting circuit of an automatic, passive infrared motion sensor controlled, speed regulator switch for ceiling fans. The circuit, designed for AC230V operation is realized using generally available discrete components, and optimized for […]
Getting knew about embedded systems is toilsome for an engineering graduate and a fresher who has just passed out. To learn the basic concepts and get an overview of embedded systems here are the 7 […]
Validating the calibration of an electronic test and measurement instrument such as a digital voltmeter (DVM) is very crucial especially after many years of service. Nowadays, it is easy to build a compact voltage reference […]
