470K 16mm Rotary Pot(Pack of 5) Documentation

Component Name

470K 16mm Rotary Pot (Pack of 5)

Overview

The 470K 16mm Rotary Pot is a type of potentiometer designed for various applications in the Internet of Things (IoT) and electronics projects. This component is a variable resistor that allows for the division of voltage into two parts, enabling the creation of a voltage signal that is proportional to the rotation of the shaft.

Functionality

The primary function of the 470K 16mm Rotary Pot is to convert the mechanical rotation of the shaft into an electrical signal. This is achieved through a resistive track that is connected to the three terminals of the potentiometer. When the shaft is rotated, the wiper (the movable contact) slides along the resistive track, dividing the input voltage into two parts. The output voltage, which is taken from the wiper terminal, is proportional to the rotation of the shaft, making it an ideal component for applications that require position sensing, volume control, and signal adjustment.

Overview
The 470K 16mm Rotary Pot is a 3-pin rotary potentiometer with a resistance of 470k and a compact size of 16mm. It is commonly used in IoT projects and electronic designs to provide adjustable resistance or voltage division. This documentation explains the functionality of each pin and provides a step-by-step guide on how to connect them.
Pin Description
1. Pin 1: CLK (Clockwise) or Terminal 1
Functionality: This pin is connected to one end of the internal resistor network and represents the "clockwise" or "high" side of the potentiometer.
Connection: Normally connected to the power supply (VCC) or a fixed voltage source.
2. Pin 2: WIPER (Center) or Terminal 2
Functionality: This pin is connected to the movable wiper contact of the potentiometer, which varies the resistance as the pot is rotated.
Connection: Typically connected to the input or output of a circuit, such as a voltage divider or an analog-to-digital converter.
3. Pin 3: CTR (Counterclockwise) or Terminal 3
Functionality: This pin is connected to the other end of the internal resistor network and represents the "counterclockwise" or "low" side of the potentiometer.
Connection: Normally connected to ground (GND) or a reference voltage.
Connection Structure
Here is a general connection structure for the 470K 16mm Rotary Pot:
Power Supply (VCC) or Fixed Voltage Source:
+ Connect Pin 1 (CLK) to the positive terminal of the power supply or fixed voltage source.
Input/Output Circuit:

Code Examples

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

In this example, we'll use the rotary potentiometer as a voltage divider to control the brightness of an LED.

Hardware Requirements

Arduino Board (e.g., Arduino Uno)
 470K 16mm Rotary Pot (Pack of 5)
 LED
 220 resistor
 Breadboard and jumper wires

Code
```c++
const int potPin = A0;  // Select analog input pin for rotary pot
const int ledPin = 9;  // Select digital output pin for LED

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

void loop() {
  int sensorValue = analogRead(potPin);  // Read analog value from rotary pot
  int brightness = map(sensorValue, 0, 1023, 0, 255);  // Map sensor value to LED brightness (0-255)
  analogWrite(ledPin, brightness);  // Set LED brightness
  delay(10);
}
```
In this example, the rotary potentiometer is connected to analog input pin A0 on the Arduino board. The `analogRead()` function reads the analog value from the potentiometer, which is then mapped to an LED brightness value using the `map()` function. The resulting brightness value is written to the LED using the `analogWrite()` function.

### Example 2: Digital Control using a Microcontroller (Raspberry Pi)

In this example, we'll use the rotary potentiometer to control a digital output on a Raspberry Pi.

Hardware Requirements

Raspberry Pi (e.g., Raspberry Pi 4)
 470K 16mm Rotary Pot (Pack of 5)
 Breadboard and jumper wires

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

# Set up GPIO mode
GPIO.setmode(GPIO.BCM)

# Define pins
pot_pin = 17  # GPIO 17 as input for rotary pot
out_pin = 23  # GPIO 23 as output

# Set up input and output pins
GPIO.setup(pot_pin, GPIO.IN)
GPIO.setup(out_pin, GPIO.OUT)

while True:
    # Read digital value from rotary pot
    pot_value = GPIO.input(pot_pin)

# Toggle digital output based on pot value
    if pot_value:
        GPIO.output(out_pin, GPIO.HIGH)
    else:
        GPIO.output(out_pin, GPIO.LOW)

time.sleep(0.01)
```
In this example, the rotary potentiometer is connected to GPIO 17 on the Raspberry Pi. The `GPIO.input()` function reads the digital value from the potentiometer, which is then used to toggle a digital output on GPIO 23 using the `GPIO.output()` function.

Additional Notes

When using the rotary potentiometer, ensure that the circuit is properly debounced to prevent false triggering.
 The rotary potentiometer's mechanical life is limited; avoid excessive rotation or vibration to prolong its lifespan.

By following these examples and technical specifications, you can effectively integrate the 470K 16mm Rotary Pot (Pack of 5) into your IoT projects, leveraging its precision and compact design to achieve a wide range of analog and digital control applications.
