Crowtail- Linear Potentiometer

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.

Model: CT0022LP

Feature¶

• 30 mm long slide length
• Linear resistance taper
• Connection Mode:A(Analog)

Specification¶

Dimensions(mm):60.0(L)x20.0(W)x18.0(H)

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.
