Relais Drum Machine
Basic example to control on/off speed of three relais using three sensors.
/* relais drum machiine
*
* using 3 sensors to control on/off speed of 3 relais (e.g. distance sensor)
*
* based on the examples "Toggle led" and "Metro"
*
* uses metro library (http://www.arduino.cc/playground/Code/Metro)
*
* SensorAktor Workshop
* Lab3 2008
* Kunsthochschule fuer Medien Koeln
* 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

Files needed
Since Arduino 0015 there are some problems with the old “SensorAktor.h” file.
Use this one instead.
