Servo Motor Controller
Basic example to control a servo motor using built-in poti of SensorAktor-Shield.

* using poti to control servo

* Making Things, http://makingthings.andreasmuxel.com
* Based on the SensorAktor-Basics of the Lab3, Academy of Media Arts Cologne
* http://interface.khm.de
* pin mapping SensorAktor Shield
* import SensorAktor.h to get already defined mapping
*
* analog inputs: analog0 = pin0, analog1 = pin1, analog2 = pin2,
* analog3 = pin3, analog4 = pin4, analog5 = pin5
* built-in poti: poti = pin5
* amplified input: mic = pin0
* switches: switch1 = pin1, switch2 = pin2, switch3 = pin3
* leds: led1 = pin3, led2 = pin5, led3 = pin6
* power outs: out1 = pin3, out2 = pin5, out3 = pin6
* motor outs: motor1_1 = pin8, motor1_2 = pin13, motor2_1 = pin11, motor2_2 = pin12
* motor pwms: pwmMotor1 = pin10, pwmMotor2 = pin9
* servo outs: servo1 = pin2, servo2 = pin4, servo3 = pin7
