Pin Configuration

2K 3386P Trimpot (Pack of 5) - Pinout and Connection Guide
The 2K 3386P Trimpot is a 3-terminal variable resistor or potentiometer, commonly used in electronic circuits for adjusting signal levels, voltage dividers, and impedance matching. Each package contains 5 pieces of the trimpot. Here is a detailed explanation of the pins and how to connect them:
Pinout:
The 2K 3386P Trimpot has three pins, labeled as follows:
1. Pin 1 (CW): Clockwise Terminal
Function: This pin is connected to the movable wiper terminal of the trimpot.
Description: When the trimpot's shaft is turned clockwise, the resistance between Pin 1 and Pin 3 increases, while the resistance between Pin 1 and Pin 2 decreases.
2. Pin 2 (CCW): Counterclockwise Terminal
Function: This pin is connected to one end of the resistor network.
Description: When the trimpot's shaft is turned counterclockwise, the resistance between Pin 2 and Pin 3 decreases, while the resistance between Pin 2 and Pin 1 increases.
3. Pin 3 (Wiper): Wiper Terminal
Function: This pin is connected to the other end of the resistor network and is also connected to the movable wiper terminal.
Description: The wiper terminal is the output terminal of the trimpot, and its voltage varies according to the position of the shaft.
Connection Structure:
Here's a step-by-step guide on how to connect the pins of the 2K 3386P Trimpot:
Variable Voltage Divider:
Connect Pin 1 (CW) to Vcc (positive voltage supply) or a fixed voltage source.
Connect Pin 2 (CCW) to GND (ground) or a fixed voltage reference point.
Connect Pin 3 (Wiper) to the output terminal of your circuit, where you want to get a variable voltage.
Example Circuit:
Suppose you want to create a simple voltage divider circuit using the 2K 3386P Trimpot to get a variable output voltage between 0V and 5V. You can connect the pins as follows:
Pin 1 (CW) to 5V (positive voltage supply)
Pin 2 (CCW) to GND (ground)
Pin 3 (Wiper) to the output terminal of your circuit, where you want to get a variable voltage between 0V and 5V.
By turning the shaft of the trimpot, you can adjust the output voltage between 0V and 5V, according to the desired level.

Code Examples

### Example 1: Analog Voltage Divider with Arduino

In this example, we will use the 2K 3386P Trimpot to create an analog voltage divider circuit with an Arduino board.

Circuit Diagram

R1 (2K 3386P Trimpot) - VCC - R2 (1k) - GND
|                       |
A0 (Analog Input)

Code
```c++
const int POT_PIN = A0;  // Analog input pin

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

void loop() {
  int sensorValue = analogRead(POT_PIN);
  float voltage = sensorValue  (5.0 / 1023.0);
  Serial.print("Voltage: ");
  Serial.print(voltage);
  Serial.println("V");
  delay(500);
}
```
In this example, the 2K 3386P Trimpot is used to divide the voltage between VCC and GND, creating an analog signal that is read by the Arduino's analog input pin (A0). The code reads the analog value and converts it to a voltage reading, which is then printed to the serial monitor.

### Example 2: Audio Volume Control with Raspberry Pi

In this example, we will use the 2K 3386P Trimpot to control the volume of an audio signal using a Raspberry Pi.

Circuit Diagram

|                       |
GPIO 18 (PWM Output)

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

GPIO.setmode(GPIO.BCM)
GPIO.setup(18, GPIO.OUT)

p = GPIO.PWM(18, 50)  # 50Hz PWM frequency

while True:
    pot_value = GPIO.input(18)  # Read POT value
    pwm_duty_cycle = pot_value  (100.0 / 1023.0)
    p.ChangeDutyCycle(pwm_duty_cycle)
    time.sleep(0.01)
```
In this example, the 2K 3386P Trimpot is used to adjust the PWM duty cycle of the Raspberry Pi's GPIO 18 pin, which controls the volume of an audio signal. The code reads the POT value and sets the PWM duty cycle accordingly, allowing for smooth volume control.

### Example 3: LED Dimming with ESP32

In this example, we will use the 2K 3386P Trimpot to dim an LED connected to an ESP32 board.

Circuit Diagram

R1 (2K 3386P Trimpot) - LED - R2 (1k) - GND
|                       |
GPIO 2 (Digital Output)

Code
```c++
#include <WiFi.h>

const int LED_PIN = 2;  // Digital output pin

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

void loop() {
  int pot_value = analogRead(2);  // Read POT value
  int brightness = map(pot_value, 0, 1023, 0, 255);
  analogWrite(LED_PIN, brightness);
  delay(10);
}
```
In this example, the 2K 3386P Trimpot is used to adjust the brightness of an LED connected to the ESP32's digital output pin (GPIO 2). The code reads the POT value and sets the LED brightness accordingly using the `analogWrite()` function.

These examples demonstrate the versatility of the 2K 3386P Trimpot in various IoT applications, including analog voltage division, audio volume control, and LED dimming.
