5K ohm 16mm Rotatory Variable Potentiometer (Pack of 5) Documentation

Component Name

5K ohm 16mm Rotatory Variable Potentiometer (Pack of 5)

Description

The 5K ohm 16mm Rotatory Variable Potentiometer is a type of variable resistor used to regulate electrical signals in various applications. This component is a rotary potentiometer, meaning its resistance value can be adjusted by rotating a shaft. It is a popular choice for IoT projects, robotics, and other electronic systems that require manual adjustment of voltage or current.

Functionality

The primary function of this potentiometer is to divide a voltage source into two parts, allowing the user to adjust the proportion of voltage between the two outputs. This is achieved by varying the resistance between the input and output terminals. When the shaft is rotated, the wiper (the moving contact) slides along the resistive material, changing the resistance ratio between the input and output.

Pin Configuration

Component Overview:
The 5K ohm 16mm Rotatory Variable Potentiometer is a type of electronic component that varies its resistance in response to rotational movement. It is commonly used to divide a voltage source into two parts, creating an adjustable voltage divider. This documentation explains the pin configuration and connection guide for the 5K ohm 16mm Rotatory Variable Potentiometer.
Pin Configuration:
The 5K ohm 16mm Rotatory Variable Potentiometer has three pins, labeled as follows:
1. Pin 1: CCW (Counter-ClockWise) Terminal
This pin is connected to one end of the potentiometer's resistive track.
It is typically connected to a fixed voltage source, such as Vcc or 5V.
2. Pin 2: Wiper Terminal
This pin is connected to the movable wiper contact, which slides along the resistive track as the potentiometer is rotated.
It is typically connected to the output of the voltage divider or to an analog input of a microcontroller.
3. Pin 3: CW (ClockWise) Terminal
This pin is connected to the other end of the potentiometer's resistive track.
It is typically connected to ground (GND) or a fixed voltage source, depending on the application.
Connection Guide:
Here is a step-by-step guide to connect the pins:
Connection Structure:
Connection 1: Power Supply
+ Connect Pin 1 (CCW Terminal) to a fixed voltage source, such as Vcc or 5V.
Connection 2: Wiper Output
+ Connect Pin 2 (Wiper Terminal) to the output of the voltage divider or to an analog input of a microcontroller.
Connection 3: Ground or Fixed Voltage
+ Connect Pin 3 (CW Terminal) to ground (GND) or a fixed voltage source, depending on the application.
Tips and Precautions:
Make sure to handle the potentiometer carefully to avoid damage or deformation of the resistive track.
Use a suitable rotary knob or shaft to rotate the potentiometer, ensuring smooth and consistent movement.
Avoid over-tightening or over-loosening the potentiometer, as this can damage the internal mechanisms.
When connecting the potentiometer, ensure that the pins are securely connected to the circuit board or breadboard to prevent loose connections.
By following these guidelines, you can effectively use the 5K ohm 16mm Rotatory Variable Potentiometer in your IoT projects.

Code Examples

### Example 1: Basic Analog Voltage Divider (Arduino)

In this example, we will use the potentiometer to create an analog voltage divider, controlling the output voltage using the rotary mechanism.

```c++
const int potentPin = A0;  // Potentiometer wiper connected to Analog Input 0
const int ledPin = 9;    // LED connected to Digital Pin 9

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

void loop() {
  int potentValue = analogRead(potentPin);
  int outputValue = map(potentValue, 0, 1023, 0, 255);
  analogWrite(ledPin, outputValue);
  delay(20);
}
```

In this code, the `analogRead()` function reads the voltage at the potentiometer's wiper terminal, which varies between 0 and 1023. The `map()` function scales this value to a range suitable for the LED's brightness (0 to 255). Finally, `analogWrite()` sets the LED's brightness accordingly.

### Example 2: Reading Rotary Position (Raspberry Pi with Python)

In this example, we will use the potentiometer to read the rotary position and display it on the console.

```python
import RPi.GPIO as GPIO
import time

GPIO.setmode(GPIO.BCM)

potent_pin = 17  # Potentiometer wiper connected to GPIO 17
GPIO.setup(potent_pin, GPIO.IN)

while True:
    potent_value = GPIO.input(potent_pin)
    rotary_position = (potent_value / 1023)  300  # Scale to 0-300 degrees
    print("Rotary Position: {:.2f} degrees".format(rotary_position))
    time.sleep(0.1)
```

In this code, we use the RPi.GPIO library to read the digital value at the potentiometer's wiper terminal. We scale this value to a range of 0 to 300 degrees, representing the rotary position, and print it to the console.

Note: These examples assume a basic understanding of the respective platforms (Arduino and Raspberry Pi) and programming languages (C++ and Python). Always ensure proper connections and voltage levels when working with electronic components.
