Proximity Detector using Hall Effect Sensor Circuit
This proximity detector circuit uses a Hall effect sensor to detect the approach of a magnetic object, such as a magnet fixed to the frame of a door. The application […]
Windshield Washer Fluid Indicator Circuit
In this article I have explained a permanent indicator of the windshield washer fluid level. Knowing that electronics do not mix well with liquids, instead of using a float gauge […]
Child Crying Monitor Circuit using Power Line Communication
In this child crying monitor circuit when the baby wakes up in their room, the parents are immediately notified, even if they are in another room of their home. A […]
Diodes: Working, How to Use, Applications
It’s John Ambrose Fleming (1849-1945), a British engineer, who invented the first diode in 1904, in the form of an electron tube. Later, with the development of semiconductor technology, the […]
IC 7805 Switching Regulator Circuit
Starting from a classical linear regulation, we will present the evolution towards a simple switching version. This will allow us to analyze the operation without going through the classical theoretical […]
