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 ...

LED Blinking: We use an LED (Light Emitting Diode), which is connected to the Arduino via a resistor. The resistor limits the current that flows through the LED to prevent it from burning by too much ...
