Description

The 1K Pot Potentiometer is a type of variable resistor that allows for precise adjustment of electrical resistance. It is a compact, rotary-style potentiometer that comes in a pack of 5 units. This component is commonly used in a wide range of applications, including analog circuit design, audio equipment, and robotics.

The primary function of the 1K Pot Potentiometer is to vary the resistance of an electrical circuit. It achieves this by using a rotary shaft that moves a wiper contact along a resistive material, dividing the resistance into two variable resistors. By turning the shaft, the user can adjust the resistance ratio between the two terminals, allowing for fine-tuned control over the circuit's overall resistance.

Pin Configuration

1K Pot Potentiometer - (Pack of 5) Documentation
Overview
The 1K Pot Potentiometer is a variable resistor that provides a linear output voltage in response to mechanical rotations. This documentation explains the pinout and connection guidelines for the 1K Pot Potentiometer, which comes in a pack of 5.
Pinout
The 1K Pot Potentiometer has three pins, labeled 1, 2, and 3. Here's a detailed explanation of each pin:
Pin 1:
Function: Output pin (Wiper)
Description: This pin is connected to the moving contact (wiper) of the potentiometer. As the potentiometer shaft is rotated, the voltage at this pin changes linearly with respect to the input voltage applied between pins 2 and 3.
Typical Connection: Connect to an analog input pin of a microcontroller or analog-to-digital converter (ADC) to read the voltage output.
Pin 2:
Function: High-side input pin
Description: This pin is connected to one end of the resistive track and provides the high-side input voltage.
Typical Connection: Connect to a positive voltage supply (e.g., VCC) or a voltage reference point.
Pin 3:
Function: Low-side input pin
Description: This pin is connected to the other end of the resistive track and provides the low-side input voltage.
Typical Connection: Connect to a negative voltage supply (e.g., GND) or a voltage reference point.
Connection Guidelines
To use the 1K Pot Potentiometer, follow these connection guidelines:
1. Connect Pin 2 to a positive voltage supply (VCC): This provides the high-side input voltage.
2. Connect Pin 3 to a negative voltage supply (GND): This provides the low-side input voltage.
3. Connect Pin 1 to an analog input pin of a microcontroller or ADC: This allows you to read the output voltage from the potentiometer.

Important Notes
Ensure the voltage supply is within the recommended operating range for the potentiometer (typically 0V to 5V).
Use a suitable voltage reference point if you're not connecting to a dedicated voltage supply.
Avoid applying excessive mechanical stress or rotation to the potentiometer shaft to prevent damage.
By following these connection guidelines and pinout explanations, you can effectively use the 1K Pot Potentiometer in your IoT projects.

Overview

The 1K Pot Potentiometer is a rotary potentiometer with a linear taper and a resistance value of 1k. It is a common component used in various electronic circuits to provide a variable voltage or resistance. This pack includes 5 units of the 1K Pot Potentiometer.

Pinout

The 1K Pot Potentiometer has three terminals:

1. CCW (Counter-Clockwise): The terminal connected to the counter-clockwise end of the potentiometer.
2. Wiper: The movable terminal that provides a variable voltage or resistance.
3. CW (Clockwise): The terminal connected to the clockwise end of the potentiometer.

Code Examples

### Example 1: Reading Potentiometer Value using Arduino

In this example, we will use an Arduino board to read the value of the potentiometer and display it on the serial monitor.

Components:

1K Pot Potentiometer
 Arduino Board (e.g., Arduino Uno)
 Breadboard
 Jumper Wires

Connections:

Connect the CCW terminal of the potentiometer to GND on the Arduino board.
 Connect the Wiper terminal of the potentiometer to Analog Input A0 on the Arduino board.
 Connect the CW terminal of the potentiometer to VCC (5V) on the Arduino board.

Code:
```c++
const int potPin = A0;  // Analog input pin for potentiometer

void setup() {
  Serial.begin(9600);
}

void loop() {
  int potValue = analogRead(potPin);
  Serial.print("Potentiometer Value: ");
  Serial.println(potValue);
  delay(50);
}
```
This code reads the analog value of the potentiometer using the `analogRead()` function and prints it to the serial monitor.

### Example 2: Using Potentiometer as a Voltage Divider

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

Components:

1K Pot Potentiometer
 LED
 1k Resistor
 Breadboard
 Jumper Wires
 Power Supply (e.g., 9V Battery)

Connections:

Connect the CCW terminal of the potentiometer to GND.
 Connect the Wiper terminal of the potentiometer to the anode of the LED.
 Connect the CW terminal of the potentiometer to the positive terminal of the power supply (9V).
 Connect the cathode of the LED to the 1k Resistor.
 Connect the other end of the 1k Resistor to GND.

Theory:

The potentiometer acts as a voltage divider, providing a variable voltage to the LED. As the potentiometer is rotated, the voltage across the LED changes, controlling its brightness.

Note: Make sure to use a suitable power supply and resistor value to prevent damage to the LED.

These examples demonstrate the basic usage of the 1K Pot Potentiometer. You can use this component in various other applications, such as audio circuits, motor control, and sensor circuits, by adjusting the connections and code according to your specific requirements.
