| In an interrupt scheme, the microcontroller does essentially nothing in its main loop, but it is directed to do something specific when an input source jostles it into action. | In an interrupt scheme, the microcontroller does essentially nothing in its main loop, but it is directed to do something specific when an input source jostles it into action. | ||

| The following examples use polling to determine the state of a switch. If the switch is pressed, the Arduino will turn an LED on. If it is not pressed, it will turn the LED off. | The following examples use polling to determine the state of a switch. If the switch is pressed, the Arduino will turn an LED on.
