Pin Configuration

1M 3386P Trimpot (Pack of 5) Documentation
Overview
The 1M 3386P Trimpot is a type of potentiometer, a variable resistor, commonly used in electronic circuits to adjust voltage, impedance, or signal levels. This trimmer potentiometer is a compact, axial-lead device with a resistance value of 1M ohms.
Pinout
The 1M 3386P Trimpot has three pins, which are explained below:
Pin 1: Counter Clockwise (CCW) Terminal
Function: Connects to the low-end (0%) of the resistance range
Description: This pin is the counter-clockwise terminal of the potentiometer, which is connected to the low-end of the resistance range (0% of the total resistance value).
Pin 2: Wiper Terminal
Function: Connects to the moving contact (wiper) of the potentiometer
Description: This pin is the wiper terminal, which is connected to the moving contact of the potentiometer. The wiper terminal is connected to the output of the potentiometer, and its position determines the resistance ratio between the CCW and CW terminals.
Pin 3: Clockwise (CW) Terminal
Function: Connects to the high-end (100%) of the resistance range
Description: This pin is the clockwise terminal of the potentiometer, which is connected to the high-end of the resistance range (100% of the total resistance value).
Connection Structure
To connect the 1M 3386P Trimpot, follow these steps:
1. CCW Terminal (Pin 1): Connect the CCW terminal to a fixed voltage source (e.g., Vcc or GND) or a signal ground.
2. Wiper Terminal (Pin 2): Connect the wiper terminal to the output of your circuit, which requires a variable resistance or voltage divider.
3. CW Terminal (Pin 3): Connect the CW terminal to the other fixed voltage source (e.g., Vcc or GND) or a signal ground.
Important Notes
The potentiometer's resistance value is 1M ohms, so ensure that your circuit is designed to accommodate this value.
When adjusting the trimmer potentiometer, turn the knob clockwise to increase the resistance or counter-clockwise to decrease the resistance.
Use a screwdriver or a trimmer tool to adjust the potentiometer's position.
Ensure proper soldering and handling to avoid damaging the component.
By following this documentation, you can successfully connect and utilize the 1M 3386P Trimpot in your electronic projects.

 Vin --->[R1]--->| Trimpot |----->[R2]---> GND
           |           |           |
           |  Pin 1    |  Pin 2    |  Pin 3

Code Example (Arduino)
```c
const int vin = 5;  // Input voltage (5V)
const int r1 = 1000;  // Fixed resistor (1kohm)
const int trimpotPin = A0;  // Trimpot wiper pin connected to analog input 0

void setup() {
  pinMode(trimpotPin, INPUT);
  Serial.begin(9600);
}

void loop() {
  int trimpotValue = analogRead(trimpotPin);
  float outputVoltage = (trimpotValue / 1023.0)  vin;
  Serial.print("Output Voltage: ");
  Serial.print(outputVoltage);
  Serial.println(" V");
  delay(500);
}

# PyAudio setup
p = pyaudio.PyAudio()
stream = p.open(format=pyaudio.paInt16, channels=1, rate=44100, input=True, frames_per_buffer=1024)

while True:
    # Read audio data
    data = np.fromstring(stream.read(1024), dtype=np.int16)
    
    # Apply signal attenuation using the trimpot
    trimpotValue = 0.5  # Adjust this value to change the attenuation level
    attenuatedData = data  trimpotValue
    
    # Write attenuated data to the output
    stream.write(attenuatedData.tobytes())
```
These examples demonstrate the versatility of the 1M 3386P Trimpot in various IoT applications, including voltage regulation and signal attenuation. By adjusting the trimpot's wiper position, you can fine-tune the output voltage or signal level to meet the specific requirements of your project.
