200E 3386P Trimpot (Pack of 5) DocumentationOverviewThe 200E 3386P Trimpot is a type of potentiometer, a variable resistor used to divide a voltage source, allowing for the adjustment of signal levels, impedance matching, and voltage regulation. This trimpot is a multi-turn, ceramic-body potentiometer with a 200 nominal resistance and a power rating of 0.5W. It is commonly used in various electronic circuits, including audio equipment, sensors, and IoT devices.Pinout and DimensionsThe 200E 3386P Trimpot has a standard 3-pin configuration:Pin 1: Counter-Clockwise (CCW) terminal
Pin 2: Wiper terminal
Pin 3: Clockwise (CW) terminalThe trimpot has a compact size, making it suitable for breadboarding and PCB mounting:Length: 11.5 mm
Width: 4.5 mm
Height: 3.5 mmCode ExamplesExample 1: Analog Voltage Divider (Arduino)In this example, we'll use the trimpot to create an analog voltage divider, allowing us to adjust the output voltage of a 5V supply.```c++
const int trimpotPin = A0; // Connect trimpot wiper to analog input A0
const int outputPin = 9; // Connect output pin to an LED or a voltage metervoid setup() {
pinMode(trimpotPin, INPUT);
pinMode(outputPin, OUTPUT);
}void loop() {
int trimpotValue = analogRead(trimpotPin);
int outputValue = map(trimpotValue, 0, 1023, 0, 255);
analogWrite(outputPin, outputValue);
delay(10);
}
```Example 2: Audio Volume Control (Raspberry Pi - Python)In this example, we'll use the trimpot to control the audio volume of a Raspberry Pi.```python
import RPi.GPIO as GPIO
import pygame# Set up GPIO mode and trimpot pin
GPIO.setmode(GPIO.BCM)
trimpot_pin = 18
GPIO.setup(trimpot_pin, GPIO.IN)# Initialize pygame mixer
pygame.mixer.init()while True:
trimpot_value = GPIO.input(trimpot_pin)
volume = trimpot_value / 1023.0 # Scale trimpot value to 0.0 - 1.0 range
pygame.mixer.music.set_volume(volume)
```Example 3: Sensor Signal Conditioning (ESP32 - MicroPython)In this example, we'll use the trimpot to condition a sensor signal, such as a photodiode or thermistor, and read the output voltage using an ESP32.```python
import machine# Set up trimpot pin and ADC
trimpot_pin = machine.Pin(32)
adc = machine.ADC(trimpot_pin)while True:
sensor_value = adc.read_u16() # Read 16-bit ADC value
voltage = sensor_value / 65535.0 3.3 # Scale ADC value to voltage (0-3.3V range)
print("Sensor voltage: {:.2f} V".format(voltage))
machine.delay(50)
```These examples demonstrate the versatility of the 200E 3386P Trimpot in various IoT applications.
