This example shows you how to read analog input from the physical world using a potentiometer. Apotentiometeris a simple mechanical device that provides a varying amount of resistance when its shaft is turned. By passing voltage through a potentiometer and into an analog input on your board, it...
AnalogReadSerial- Read a potentiometer, print its state out to the Arduino Serial Monitor. BareMinimum- The bare minimum of code needed to start an Arduino sketch. DigitalReadSerial- Read a switch, print the state out to the Arduino Serial Monitor. Fade- Demonstrates the use of analog output ...
