Pin Configuration

Component Overview
The 200E 3296W Trimpot is a popular variable resistor, also known as a trimpot, used for precision adjustment of circuit parameters. This documentation explains the pinout and connection details for the 200E 3296W Trimpot (Pack of 5).
Pinout
The 200E 3296W Trimpot has 3 pins, labeled as follows:
Pin 1:
Function: Counter Clockwise (CCW) Terminal
Purpose: Connects to the lower end of the resistive element
Characteristics: When the shaft is turned counterclockwise, the resistance between Pin 1 and Pin 2 increases, while the resistance between Pin 1 and Pin 3 decreases.
Pin 2:
Function: Wiper Terminal
Purpose: Connects to the moving contact (wiper) of the resistive element
Characteristics: The wiper terminal is connected to the midpoint of the resistive element. When the shaft is turned, the wiper moves along the resistive element, changing the resistance between Pin 2 and Pin 1/Pin 3.
Pin 3:
Function: Clockwise (CW) Terminal
Purpose: Connects to the upper end of the resistive element
Characteristics: When the shaft is turned clockwise, the resistance between Pin 3 and Pin 2 increases, while the resistance between Pin 3 and Pin 1 decreases.
Connection Diagram
Here's a step-by-step guide to connecting the pins:
1. Pin 1 (CCW Terminal):
Connect to a fixed voltage source (e.g., Vcc) or a fixed reference point in the circuit.
Ensure a stable connection to prevent unwanted changes in resistance.
2. Pin 2 (Wiper Terminal):
Connect to the point in the circuit where the variable resistance is required (e.g., a voltage divider, filter, or gain control).
The wiper terminal should be connected to a point that requires adjustment, such as a signal input or output.
3. Pin 3 (CW Terminal):
Connect to a fixed voltage source (e.g., GND) or a fixed reference point in the circuit.
Ensure a stable connection to prevent unwanted changes in resistance.
Important Notes:
When using the trimpot, ensure that the shaft is turned gently and gradually to avoid damaging the internal mechanism.
The trimpot's resistance value is typically measured between Pin 1 and Pin 3, with the wiper terminal (Pin 2) at its midpoint.
The 200E 3296W Trimpot has a linear taper, meaning that the resistance change is proportional to the shaft rotation.
By following these guidelines, you can successfully incorporate the 200E 3296W Trimpot into your IoT project and achieve precise control over circuit parameters.

Pinout

The 200E 3296W Trimpot has three pins:

Pin 1: CCW (Counter-Clockwise) terminal
 Pin 2: Wiper terminal
 Pin 3: CW (Clockwise) terminal

Code Examples

Example 1: Analog Voltage Divider (Arduino)
```c
const int trimPotPin = A0;  // Analog input pin connected to Trimpot wiper
const int outputPin = 9;  // Digital output pin

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

void loop() {
  int trimPotValue = analogRead(trimPotPin);
  int outputValue = map(trimPotValue, 0, 1023, 0, 255);
  analogWrite(outputPin, outputValue);
  delay(50);
}
```
In this example, the Trimpot is used as an analog voltage divider to control the brightness of an LED connected to digital output pin 9. The Arduino reads the Trimpot value using the `analogRead()` function and maps it to a digital output value using the `map()` function.

Example 2: Volume Control (Raspberry Pi Python)
```python
import RPi.GPIO as GPIO

GPIO.setmode(GPIO.BCM)

trimPotPin = 17  # GPIO pin connected to Trimpot wiper
outputPin = 23  # GPIO pin connected to audio amplifier

GPIO.setup(trimPotPin, GPIO.IN)
GPIO.setup(outputPin, GPIO.OUT)

while True:
    trimPotValue = GPIO.input(trimPotPin)
    if trimPotValue == GPIO.HIGH:
        GPIO.output(outputPin, GPIO.HIGH)
    else:
        GPIO.output(outputPin, GPIO.LOW)
    time.sleep(0.1)
```
In this example, the Trimpot is used as a digital volume control for an audio amplifier connected to a Raspberry Pi. The Python script reads the Trimpot value using the `GPIO.input()` function and sets the output pin high or low depending on the Trimpot position.

Example 3: Sensor Calibration (ESP32 MicroPython)
```python
import machine

trimPotPin = machine.Pin(32, machine.Pin.IN)  # Trimpot wiper connected to ESP32 GPIO 32
sensorPin = machine.Pin(35, machine.Pin.IN)  # Sensor connected to ESP32 GPIO 35

while True:
    trimPotValue = trimPotPin.value()
    sensorValue = sensorPin.value()
    adjustedSensorValue = sensorValue  (trimPotValue / 1023.0)
    print("Adjusted sensor value:", adjustedSensorValue)
    time.sleep(0.1)
```
In this example, the Trimpot is used to calibrate a sensor connected to an ESP32 board. The MicroPython script reads the Trimpot value and uses it to adjust the sensor reading, providing a calibrated output value.
