This project demonstrates how to control the brightness of an LED using a potentiometer. The analog input from the potentiometer is mapped to control the PWM output, adjusting the LED brightness ...

Using the input from a potentiometer ... can always play again by pressing the Arduino's built-in reset button. A KiCad schematic is conveniently included on how to wire the hardware. Note that the ...

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 ...
