In this tutorial, we will learn about simple inverter circuits that anyone can understand and build easily; also these circuits require only a few components and use no ICs or complex designs. Just two power transistors and a transformer and it converts 12V battery power into AC supply which is good for beginners and DIY […]
Simple 9V Transistor Inverter Circuit
This is Simple 9V Transistor Inverter Circuit using 9V battery, which is very small and easy to make and which helps to understand DC to AC working. Circuit uses only few low cost parts and its output power is very low and also it is only for testing and learning and further is useful for […]
Arduino DC Motor Controller Circuit using MOSFET
This project is about controlling DC motor with Arduino and MOSFET, as MOSFET is small electronic part but very strong which can handle big current. Arduino cannot drive big motor directly, so MOSFET help Arduino to run motor safely; therefore, this Arduino DC Motor Controller Circuit using MOSFET is simple, safe and cheap. Arduino Code: […]
Arduino Based 55W Halogen Light Controller Circuit
To begin with, this project controls a 55W halogen lamp using an Arduino, here, the Arduino provides a low-voltage signal, while the MOSFET handles the high voltage and high current. Also, this circuit is useful for dimming, ON/OFF control and automation projects. Arduino Code: Circuit Working: Parts List: Components Values Quantity Resistor 1k 1/4 watt […]
Soft ON Circuit for 12V Halogen Lamp
In this post halogen lamp draws very high current at switch ON, then cold filament resistance is very low and this causes sudden inrush current. Lamp life becomes short, then this circuit protects lamp and it also protects outside fuse and switch indirectly; therefore, Soft ON Circuit for 12V Halogen Lamp reduces this problem. Lamp […]
Simple Transistor Based Touch Switch Circuit
This article is about a Simple Transistor Based Touch Switch Circuit, it works when finger touches the pad with no push button used; human body gives small signal and circuit senses this signal. The circuit uses two NPN transistors and an LED as the output, also it operates with only a 3V supply, making it […]
