Potentiometers are one of the most common input devices you’ll find in electronics projects. They’re often used to control things like audio volume, screen brightness, or even robot speed. In this ...

This Arduino project demonstrates how an analog input device can be used to control the brightness of an LED in real time. By rotating a potentiometer, the Arduino continuously measures the changing ...

A simple virtual Arduino project demonstrating LED brightness control using a potentiometer in TinkerCAD. The potentiometer's analog value (0–1023) is read and mapped to a PWM range (0–255) to ...

Last time, we used a push button to control an LED. Pressing the button turns the LED on, and releasing it turns it off. It is a very simple circuit, but Input → Arduino → Output we were able to ...

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 ...
