Pin Configuration

Component Documentation: 2M 3296W Trimpot (Pack of 5)
Overview
The 2M 3296W Trimpot is a multi-turn trimmer potentiometer, commonly used in electronic circuits for precise adjustment of resistance values. This documentation provides a detailed explanation of the pins and how to connect them.
Pinout
The 2M 3296W Trimpot has three pins, labeled 1, 2, and 3. Here's a breakdown of each pin's function:
Pin 1:
Function: Counter-Clockwise (CCW) Terminal
Description: This pin is connected to one end of the resistive track. When the trimmer is adjusted, the resistance between Pin 1 and Pin 2 changes.
Pin 2:
Function: Wiper Terminal
Description: This pin is connected to the movable wiper contact, which slides along the resistive track as the trimmer is adjusted. The wiper terminal is the output of the potentiometer, providing the adjusted resistance value.
Pin 3:
Function: Clockwise (CW) Terminal
Description: This pin is connected to the other end of the resistive track. When the trimmer is adjusted, the resistance between Pin 3 and Pin 2 changes.
Connection Structure
To connect the 2M 3296W Trimpot, follow this step-by-step guide:
1. Counter-Clockwise (CCW) Terminal (Pin 1):
Connect Pin 1 to the power supply or a fixed reference voltage (e.g., Vcc).
Typically, Pin 1 is connected to a higher voltage or the positive rail of the power supply.
2. Wiper Terminal (Pin 2):
Connect Pin 2 to the output of the circuit, where the adjusted resistance value is required.
This may include a microcontroller's analog input, an op-amp's input, or any other component that requires a variable resistance.
3. Clockwise (CW) Terminal (Pin 3):
Connect Pin 3 to ground or a fixed reference voltage (e.g., GND).
Typically, Pin 3 is connected to a lower voltage or the negative rail of the power supply.
Important Notes:
The trimmer potentiometer should be adjusted using a non-conductive tool (e.g., a plastic or ceramic screwdriver) to avoid damage or electrical shock.
The 2M 3296W Trimpot is a multi-turn trimmer, allowing for fine adjustments of the resistance value.
The component should be handled with care to avoid mechanical damage or misalignment of the wiper contact.
By following this documentation, you should be able to properly connect and utilize the 2M 3296W Trimpot in your electronic projects.

int ledBrightness = 0;  // Variable to store the LED brightness

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

void loop() {
  potValue = analogRead(potPin);  // Read the Trimpot value (0-1023)
  ledBrightness = map(potValue, 0, 1023, 0, 255);  // Map the value to LED brightness (0-255)
  analogWrite(ledPin, ledBrightness);  // Set the LED brightness
  delay(10);

# Set up the Trimpot pin as an analog input
GPIO.setup(trim_pot_pin, GPIO.IN)

while True:
    # Read the Trimpot value (0-1023)
    trim_pot_value = GPIO.input(trim_pot_pin)

# Calculate the volume based on the Trimpot value
    volume = trim_pot_value / 1023.0

# Set the volume using the `amixer` command
    cmd = f"amixer -D pulse sset Master {volume:.2f}%"
    os.system(cmd)

# Wait for a short period before reading the Trimpot again
    time.sleep(0.1)
