Softpot membrane potentiometer

I had a arduino mega and a softpot rectilinear potentiometer (200mm).

I would like to know how should I get started. I read through some of the posts and understand that there are 3 pins (pin 1 to 5v, middle pin to analog input of arduino board, last pin to gnd). Is there any more things that I need to take care of?

Also, I cant find simple program that can be used to test the potentiometer. Is there any codes that I can try out?

as the code sends the analog information to the serial port (viewable via the serial monitor), you don't need to connect the LED

Hi

I tried out the code but whenever i start running it for about 5 seconds, the arduino program hang and the serial monitor display funny symbols.

P.S: I removed the led parts in the code.

/*

const int analogInPin = A0;  // Analog input pin that the potentiometer is attached to

int sensorValue = 0;        // value read from the pot

void setup() {
   // initialize serial communications at 9600 bps:
   Serial.begin(9600); 
}

void loop() {
   // read the analog in value:
   sensorValue = analogRead(analogInPin);                     

  // print the results to the serial monitor:
   Serial.print("sensor = " );                       
   Serial.print(sensorValue);      

  // wait 10 milliseconds before the next loop
   // for the analog-to-digital converter to settle
   // after the last reading:
   delay(10);                     
}

Soft pots do not have their wiper connected to anything when not pressed. The solution is to use a pull down resistor on the analogue input, 100K to ground should be good. The only problem with this is you don't get the full range.
