Description

The Crowtail- Linear Potentiometer module uses a linear variable resistor with a maximum resistance of 10KΩ. When you move the slider from one side to the other, its output voltage will range from 0 V to the Vcc you applied. The panel mount design makes this module easy to be installed in projects.

Usage

With Arduino

Follow these simple steps to make the Linear potentiometer module function as a voltage divider:

1.When using the module in conjunction with an Arduino or a Crowduino, use the Crowtail - Base Shield and connect the Crowtail - Linear Potentiometer module to the shield using a designated Crowtail Interface (e.g., Analog Port 0 as shown below):

2.Connect the board to PC using USB cable.

3.Upload the following sample sketch:

int sensorpin=A0;
int sensorValue=0;
void setup() 
{
   Serial.begin(9600);
}
void loop()
{
  sensorValue = analogRead(sensorpin);
  Serial.print("sensorValue ");
  Serial.println(sensorValue);
}

4.Open the serial monitor. You should see some data from ADC.
