This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

A DIY night light for my bedroom using an Arduino as the processing unit, 2 LED strips for illumination which are individually controlled by one potentiometer each. Two LED strips are used to separate ...

Here is a 3D light show that will astound you with its combinations. Inexpensive and easy to make thanks to an Arduino controller, the design enables you to play with the existing effects and, most ...

Editor’s note: Last fall, EEWeb announced its inaugural design contest, sponsored by Arduino and Altium, to develop an imaginative and innovative design project of a motor control system with the ...

Abstract: This paper mainly focus on energy saving to reduce pollution using potentiometer method. There is a need to control the energy consumed by lamps in households and colleges in day time. A ...

From a simple electronic toothbrush to complicated robotics systems, DC motors are present everywhere. In most of our previous Arduino projects, we have used these DC motors as actuators and ...
