4th Project Arduino Series: Potentiometers simulate real-world input devices like volume knobs, dimmers, and control dials. This is the gateway to full analog/digital interfacing. - ...

Upload the code to your Arduino board using the Arduino IDE. Open the Serial Monitor to view the potentiometer value and LED brightness. Adjust the potentiometer to see the LED brightness change ...

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 ...

I'm trying to dim LED strips, approximately 30ft in length, with hand controls. I've found that regular potentiometers (those sold by Adafruit) max out at about 0.2 W. For whatever reason, the Red ...
