Using poti to set speed of blinking LED
Basic example to set speed of blinking LED using the built-in poti of the SensorAktor-Shield.
/* poti to blinking LED Sensor

* 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

// import sensor aktor library for pin mapping
#include <SensorAktor.h>
// poti value
int potiValue;
// this block is executed one time when programm starts
void setup(){
// set pin modes
pinMode(led1,OUTPUT);
}
// this block is executed in a loop after setup is called one time
void loop(){
// get value of poti (value between 0 and 1023)
potiValue = analogRead(poti);
// sets LED on
digitalWrite(led1,HIGH);
// wait (ms)
delay(potiValue);
// sets LED off
digitalWrite(led1,LOW);
// wait (ms)
delay(potiValue);

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