This Arduino sketch monitors the voltage output from a potentiometer connected to analog pin A0. It displays the voltage reading on the serial monitor and controls two LEDs based on the voltage level.

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 ...

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 ...
