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 ...

Sound is propagating in the form of waves. The amplitude of a wave is the distance from the centre line (or the still position) to the top of a crest or to the bottom. If you represent the sound with ...

This design idea details how a standard volume control can be replaced by its solid-state equivalent. Digital potentiometers are often advertised as replacements for rotary volume controls. To ...

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 ...

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 ...
