Circuit of a little solid-state heater controller is described here. This circuit can be used to regulate standard resistive heating coils widely used in AC230V grid supply powered heating gadgets like Air Heaters, Hot Air […]
Atomic Structure Every object and matter in this world can be broken down into smaller particles (molecules) that are invisible to our naked eye. The matter is the composition of atoms that form the material […]
Presented here is a simple yet useful AC230V White LED light bulb with an isolated digital interface to control its on/off switching actions through a microcontroller or an external electronic circuitry. The design is based […]
Inspired by a Chinese design, recently I built a small automatic LED night light with the help of a few generally available inexpensive components. Shown below is the base schematic of that automatic White LED […]
To enhance the lives of humans medical devices are critical for making invasive surgeries. Today, every medical equipment uses at least one sensor for healthcare monitoring. To meet the strict demands of medical electronics, various […]
Electronics is growing every day and recent trends in embedded systems are also happening with the Internet of things. Home appliances are talking to each other without human intervention. Robots are making home jobs and […]
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 […]
