Pin Configuration

Component Documentation: 500K 3386P Trimpot (Pack of 5)
Overview
The 500K 3386P Trimpot is a variable resistor, also known as a potentiometer, that allows for precise adjustment of resistance values. This trimmer potentiometer is commonly used in electronic circuits to adjust voltage, impedance, and signal levels. This documentation provides a detailed explanation of the pins and their connections.
Pinouts:
The 500K 3386P Trimpot has three pins, labeled A, B, and C. Here's a breakdown of each pin:
Pin A (Counter-Clockwise (CCW) Terminal):
Function: One end of the variable resistor
Description: When the trimmer potentiometer is turned counterclockwise, the resistance between Pin A and Pin C increases, while the resistance between Pin A and Pin B decreases.
Pin B (Wiper Terminal):
Function: The movable terminal that connects to the variable resistor
Description: The wiper terminal is connected to the rotating shaft of the trimmer potentiometer. As the shaft is turned, the wiper terminal slides along the resistance track, making contact with different points, effectively changing the resistance value.
Pin C (Clockwise (CW) Terminal):
Function: The other end of the variable resistor
Description: When the trimmer potentiometer is turned clockwise, the resistance between Pin C and Pin A increases, while the resistance between Pin C and Pin B decreases.
Connection Structure:
To connect the 500K 3386P Trimpot, follow this point-by-point structure:
1. Grounding: Connect Pin C (CW Terminal) to the circuit's ground or a fixed reference point. This provides a stable reference voltage.
2. Input/Signal: Connect Pin A (CCW Terminal) to the input signal or voltage source. This is the point where the variable resistance will be applied.
3. Output/Voltage Divider: Connect Pin B (Wiper Terminal) to the point in the circuit where the adjusted voltage or signal is required. This could be an amplifier, voltage regulator, or other circuit components.
Example Connection Diagram:
```
Vin ----+------> Pin A (CCW Terminal)
|
| 500K 3386P Trimpot
|
+------> Pin B (Wiper Terminal) -----> Vout
|
GND ----+------> Pin C (CW Terminal)
```
In this example, Vin is the input voltage, and Vout is the adjusted output voltage. The trimmer potentiometer is used to divide the input voltage, providing a variable output voltage.
Important Notes:
When adjusting the trimmer potentiometer, ensure that it is turned slowly and smoothly to avoid sudden changes in resistance, which could cause circuit instability or damage.
The 500K 3386P Trimpot has a maximum power rating; ensure that the circuit does not exceed this rating to prevent damage to the component.
By following this documentation, you should be able to successfully connect and utilize the 500K 3386P Trimpot in your electronic circuits.

ANALOG_INPUT_PIN = 18  # Analog input pin connected to Raspberry Pi GPIO 18

GPIO.setmode(GPIO.BCM)
GPIO.setup(TRIMPOT_PIN, GPIO.IN)

while True:
    trimpot_value = GPIO.input(TRIMPOT_PIN)
    analog_input_voltage = (trimpot_value / 1023.0)  3.3  # Calculate analog input voltage (0-3.3V)
    print("Analog input voltage:", analog_input_voltage)
    time.sleep(0.1)
```
