Presented here is an automatic motion sensor switch built around a cheap ‘Doppler Microwave Radar Sensor’ that can be easily used as standalone detection sensor. The circuit, designed as an alternative to the common PIR […]
Nowadays most electronics hobbyists require a precision 3.3V power supply module for their microcontroller (uC) and/or internet of things (IoT) projects. The traditional linear power supply is not a good choice in many situations because […]
Sensors have become an integral part of the embedded system. Right from your mobile to security systems installed at home. They are also becoming important for meteorological stations to predict weather parameters like temperature, pressure, […]
Electronics is an applied form of science that deals with electrons. It handles electric circuits containing active elements, passive elements and other underlying techniques making it as an important part of engineering. The world is […]
Recently I got a couple of powerful laser diodes from a friend abroad. The ‘invisible’ (infrared) laser diodes with 1000mW and 2000mW power (808nm wavelength) are good for numerous applications like solid-state laser excitation, infrared […]
Here is the circuit of a do it yourself universal relay module for microcontroller projects. One advantage of this design is that it can work with both active-high and active-low TTL signals from the I/O […]
Outcome of a product teardown can be used by hobbyists/makers to find out what components are being utilized in the electronic product. Such knowledge can aid understanding of how the system works, including innovative design […]
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 […]
