This pack of 5 potentiometers offers a cost-effective solution for prototyping and development. The 47K rotary potentiometer provides a smooth, continuous rotational control with a high rotational life, making it suitable for a wide range of applications.

Functionality

The 47K 16mm Rotary Potentiometer is a variable resistor that changes its resistance value in response to rotary motion. The potentiometer consists of a rotating shaft with a resistance track and three terminals

Clockwise (CW), Counter-Clockwise (CCW), and Wiper. When the shaft is rotated, the wiper terminal moves along the resistance track, dividing the total resistance into two parts. The wiper terminal provides an output voltage that is proportional to the rotation angle, allowing the potentiometer to act as a voltage divider.

47K Ohm Resistance: The potentiometer has a total resistance of 47 kilohms, providing a wide range of output voltages.
Three-Terminal Design: The potentiometer has three terminals: CW, CCW, and Wiper, allowing for easy integration into various circuits.
Rotational Angle: The potentiometer allows for a full 300 rotational angle, providing a wide range of output values.
Operating Temperature: The potentiometer operates within a temperature range of -20C to +70C, making it suitable for a wide range of applications.

Applications

Audio Applications: The potentiometer is suitable for use in audio circuits, such as volume controls, tone controls, and audio filters.
Robotics and Automation: The potentiometer can be used to control servo motors, robotic arms, and other automation systems.

Pin Configuration

47K 16mm Rotary Potentiometer (Pack of 5) - Pinout and Connection Guide
The 47K 16mm Rotary Potentiometer is a three-terminal variable resistor used to divide a voltage source into two parts. This documentation provides a detailed explanation of the pins and how to connect them.
Pinout:
The 47K 16mm Rotary Potentiometer has three pins, labeled as follows:
1. CCW (Counter-Clockwise) Terminal
Function: One end of the potentiometer's resistive track
Connecting to: Typically connected to Ground (GND) or a fixed voltage reference
2. Wiper Terminal
Function: The movable contact that slides along the resistive track, dividing the voltage
Connecting to: The output signal that varies with the potentiometer's rotation
3. CW (Clockwise) Terminal
Function: The other end of the potentiometer's resistive track
Connecting to: Typically connected to a voltage source (VCC) or a power rail
Connection Structure:
Here's a step-by-step guide to connect the pins:
Connection Example:
CCW Terminal: Connect to Ground (GND)
Wiper Terminal: Connect to an Analog-to-Digital Converter (ADC) input or a voltage amplifier/filter circuit
CW Terminal: Connect to a voltage source (VCC) or a power rail (e.g., 5V or 3.3V)
Connection Diagram:
CCW Terminal (GND) ---|---|--- Wiper Terminal (ADC Input) ---|---|--- CW Terminal (VCC)
Notes:
The CCW and CW terminals are symmetric, meaning you can swap their connections without affecting the potentiometer's operation.
The Wiper Terminal should be connected to a high-impedance input (e.g., an ADC or an op-amp) to minimize loading effects.
When using the potentiometer as a voltage divider, ensure the voltage source (VCC) is within the potentiometer's rated voltage range.
By following this documentation, you should be able to properly connect and utilize the 47K 16mm Rotary Potentiometer in your IoT projects.

Code Examples

### Example 1: Analog Reading with Arduino

This example demonstrates how to use the rotary potentiometer to control the brightness of an LED using an Arduino board.
```c
const int potPin = A0;  // Analog input pin for potentiometer
const int ledPin = 9;  // Digital output pin for LED
int ledBrightness = 0;

void setup() {
  pinMode(ledPin, OUTPUT);
}

void loop() {
  int sensorValue = analogRead(potPin);
  ledBrightness = map(sensorValue, 0, 1023, 0, 255);
  analogWrite(ledPin, ledBrightness);
  delay(10);
}
```
In this example, the rotary potentiometer is connected to analog input pin A0 of the Arduino board. The `analogRead()` function reads the analog voltage from the potentiometer, and the `map()` function scales the value to control the brightness of the LED connected to digital output pin 9.

### Example 2: Digital Reading with Raspberry Pi (Python)

This example demonstrates how to use the rotary potentiometer to control a digital output using a Raspberry Pi and Python.
```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)
pot_pin = 17  # BCM pin for potentiometer
output_pin = 23  # BCM pin for digital output

GPIO.setup(pot_pin, GPIO.IN)
GPIO.setup(output_pin, GPIO.OUT)

while True:
    pot_value = GPIO.input(pot_pin)
    if pot_value:
        GPIO.output(output_pin, GPIO.HIGH)
    else:
        GPIO.output(output_pin, GPIO.LOW)
    time.sleep(0.01)
```
In this example, the rotary potentiometer is connected to BCM pin 17 of the Raspberry Pi, and a digital output is connected to BCM pin 23. The script reads the digital value from the potentiometer using `GPIO.input()` and sets the digital output accordingly using `GPIO.output()`.

Note: These examples are for illustrative purposes only and may require modifications to work with your specific setup and use case. Consult the datasheet and component documentation for more information on using the 47K 16mm Rotary Potentiometer.
