/* | |
Analog input, analog output, serial output | |
Reads an analog input pin, maps the result to a range from 0 to 255 | |
and uses the result to set the pulsewidth modulation (PWM) of an output pin. | |
Also prints the results to the serial monitor. | |
The circuit: | |
* potentiometer connected to analog pin 0. | |
Center pin of the potentiometer goes to the analog pin. | |
side pins of the potentiometer go to +5V and ground | |
* LED connected from digital pin 9 to ground | |

Im Arduinoeditor muß "Neue Zeile" ausgewählt sein, sonst kein Feedback vom geändertem Schaltpunkt (0-255)
