Overview This project demonstrates how to control the brightness of an LED using a potentiometer (analog sensor) with an Arduino. The potentiometer’s value is read by the Arduino and mapped to control ...

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 ...

Since this library only uses three general purpose digital I/O pins, at the moment there is no compatibility issue foreseen with any model of Arduino. If you notice some incompatibility however, ...

A resistor is an electrical device that resists the flow of electrical current. In the digital era, we can find a variety of “digital resistors” for our everyday applications. This article is about ...
