Component Name

50K 3386P Trimpot (Pack of 5)

Description

The 50K 3386P Trimpot is a variable resistor, also known as a trimpot or trimmer potentiometer, designed for precise and repeatable adjustment of electrical resistance. This component is supplied in a pack of 5, making it an excellent value for prototype development, testing, and production.

Functionality

The primary function of the 50K 3386P Trimpot is to provide a variable resistance value between its three terminals. By rotating the adjustment screw, the internal wiper contact moves along the resistive track, changing the resistance value between the center terminal and the two outer terminals. This allows for precise adjustment of voltage, current, or signal levels in a circuit.

Pin Configuration

  • Component Documentation: 50K 3386P Trimpot (Pack of 5)
  • Pin Configuration and Connection Guide
  • The 50K 3386P Trimpot is a three-terminal potentiometer that allows for precise adjustable resistance divisions. It consists of five pieces in a pack, each with three pins. Below is a detailed explanation of each pin and a step-by-step connection guide:
  • Pin 1: Counter-Clockwise Terminal (CCW) or Terminal A
  • Function: This pin is connected to the end of the resistive track and is the starting point for the wiper movement when rotating the potentiometer in the counter-clockwise direction.
  • Connection: Typically connected to the positive voltage supply (VCC) or the high-side of the circuit.
  • Pin 2: Wiper Terminal (W) or Terminal B
  • Function: This pin is connected to the movable wiper contact that slides along the resistive track, dividing the resistance between Terminal A and Terminal C.
  • Connection: Typically connected to the signal or output of the circuit, which will be affected by the potentiometer's resistance division.
  • Pin 3: Clockwise Terminal (CW) or Terminal C
  • Function: This pin is connected to the other end of the resistive track and is the ending point for the wiper movement when rotating the potentiometer in the clockwise direction.
  • Connection: Typically connected to the ground (GND) or the low-side of the circuit.
  • Connection Structure:
  • Here's a general connection structure for the 50K 3386P Trimpot:
  • Connect Pin 1 (CCW) to VCC or the high-side of the circuit.
  • Connect Pin 2 (W) to the signal or output of the circuit.
  • Connect Pin 3 (CW) to GND or the low-side of the circuit.
  • Example Circuit:
  • Suppose you want to use the 50K 3386P Trimpot as a voltage divider to control the brightness of an LED. Here's a simple example circuit:
  • Connect Pin 1 (CCW) to VCC (5V).
  • Connect Pin 2 (W) to the positive leg of the LED.
  • Connect Pin 3 (CW) to GND.
  • Connect the negative leg of the LED to GND through a current-limiting resistor (e.g., 1 k).
  • By rotating the potentiometer, you can adjust the resistance division and control the voltage across the LED, thereby changing its brightness.
  • Remember to always follow proper safety precautions when working with electronics, and consult the datasheet for specific applications and usage guidelines.

  Serial.begin(9600);
}
void loop() {
  trimpotValue = analogRead(trimpotPin);
  int outputVoltage = (trimpotValue  5.0) / 1024.0;  // Calculate output voltage (0-5V)
  Serial.print("Output Voltage: ");
  Serial.print(outputVoltage);
  Serial.println(" V");
  delay(500);
}

In this example, we will use the 50K 3386P Trimpot to adjust the brightness of an LED connected to a Raspberry Pi.
```python
import RPi.GPIO as GPIO
import time
GPIO.setmode(GPIO.BCM)
trimpotPin = 17  # Select a GPIO pin on your Raspberry Pi board
ledPin = 18  # Select a GPIO pin for the LED
GPIO.setup(trimpotPin, GPIO.IN)
GPIO.setup(ledPin, GPIO.OUT)
while True:
    trimpotValue = GPIO.input(trimpotPin)
    pwm = GPIO.PWM(ledPin, 50)  # Create a PWM object with a frequency of 50 Hz
    pwm.start(0)  # Start the PWM with a duty cycle of 0%
# Adjust the duty cycle based on the trimpot value
    if trimpotValue == 0:
        pwm.ChangeDutyCycle(0)  # Minimum brightness
    elif trimpotValue == 1023:
        pwm.ChangeDutyCycle(100)  # Maximum brightness
    else:
        pwm.ChangeDutyCycle(trimpotValue / 10.23)  # Adjust brightness based on trimpot value
time.sleep(0.01)  # Adjust the sleep time to adjust the refresh rate
