100K 3386P Trimpot (Pack of 5)
100K 3386P Trimpot (Pack of 5)
The 100K 3386P Trimpot is a type of potentiometer, a variable resistor used to adjust electrical signals in a circuit. This trimpot is a compact, three-terminal device that allows for precise adjustments to be made to the signal level or voltage division ratio in a circuit. This pack of five trimpots is ideal for prototyping, testing, and production applications.
The 100K 3386P Trimpot functions as a variable resistor, allowing the user to adjust the resistance between two of its three terminals. The third terminal is connected to the movable contact, known as the wiper, which slides along the resistive element as the trimpot is turned. The trimpot acts as a voltage divider, allowing the user to set a specific voltage ratio between the input and output terminals.

100K 3386P Trimpot (Pack of 5) DocumentationOverviewThe 100K 3386P Trimpot is a type of potentiometer, a variable resistor that allows for the adjustment of circuit resistance. This component is commonly used in electronic circuits to provide a variable voltage or current signal. The 3386P is a popular trimpot model, offering a resistance range of 0 to 100 k.PinoutThe 100K 3386P Trimpot has three pins:Pin 1: CCW (Counter-ClockWise) terminal
Pin 2: Wiper terminal
Pin 3: CW (ClockWise) terminalExample 1: Basic Voltage Divider CircuitIn this example, we'll show how to use the 100K 3386P Trimpot as a voltage divider to control the output voltage of a circuit.Circuit Diagram```

Vout -> Load (e.g., LED, Resistor)
```Code Example (Arduino)
```c
const int trimpotPin = A0; // Pin connected to Wiper (Pin 2)
const int loadPin = 9; // Pin connected to Load (e.g., LED, Resistor)void setup() {
pinMode(trimpotPin, INPUT);
pinMode(loadPin, OUTPUT);
}void loop() {
int sensorValue = analogRead(trimpotPin);
int outputValue = map(sensorValue, 0, 1023, 0, 255);
analogWrite(loadPin, outputValue);
delay(10);
}
```
In this example, the trimpot is used to adjust the output voltage of the circuit, which controls the brightness of an LED or the voltage across a resistor.Example 2: Signal Attenuation CircuitIn this example, we'll demonstrate how to use the 100K 3386P Trimpot to attenuate a signal.Circuit Diagram```

```
Code Example (Python with PySerial)
```python
import serial# Open serial connection to device (e.g., Arduino, Microcontroller)
ser = serial.Serial('COM3', 9600, timeout=1)while True:
# Read trimpot value (0 to 1023)
trimpot_value = int(ser.readline().decode('utf-8'))
# Calculate attenuation factor (0 to 1)
attenuation_factor = trimpot_value / 1023.0
# Apply attenuation to signal
signal_value = signal_value attenuation_factor
# Send attenuated signal to device
ser.write(str(signal_value).encode('utf-8'))
ser.flush()
```
In this example, the trimpot is used to adjust the attenuation factor of a signal, which is then applied to the signal before sending it to a device (e.g., Op-Amp, ADC).NoteThese examples are just a few demonstrations of how to use the 100K 3386P Trimpot in various contexts. The specific code and circuit diagrams may vary depending on the application and microcontroller/device used.
