Let’s learn how to read a potentiometer, a type of rotating variable resistor, using Arduino’s analog input! We’ll connect up a simple circuit using a solderless breadboard and use some simple Arduino code to control a single LED. So far you’ve learned to control LEDs with Arduino’s output, and you learned to detect a pushbutton’s state (on […]
