A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable ...

This program uses three potentiometers for RGB control and displays the resulting color on an RGB LED. - fyemane/Arduino-Control-RGB-LED ...

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 ...

Speed Control of DC Motor using Arduino In this circuit, for controlling the speed of DC motor, we use a 100K ohm potentiometer to change the duty cycle of the PWM signal. 100K ohm potentiometer is ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

The Driver module will have four LED using which we can check which coil is being energised at any given time. The complete demonstration video can be found at the end of this tutorial. In this ...
