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 ...

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 ...

This is just a fun Arduino project that uses leds connected in circle as a ring to produce a rotation effect. You can adjust the spinning speed with a potentiometer and you can also set a minimum and ...

An Arduino sketch that blinks an LED, and an interactive teardown of it. The sketch is 49 lines. It reads a button, reads a potentiometer, and blinks an LED without ever calling delay() in the blink ...

Adjusting a fan's speed using an Arduino is a great way to learn about PWM (Pulse Width Modulation) and motor control. With just a potentiometer and some simple wiring, you can create a smooth, manual ...
