200K 3296W Trimpot (Pack of 5)
The 200K 3296W Trimpot is a type of variable resistor, also known as a trimmer potentiometer, used to adjust electrical resistance in a circuit. It is a compact, sealed potentiometer designed for precision adjustment of resistance values in a wide range of applications, including electronic circuits, instrumentation, and industrial control systems.
The primary function of the 200K 3296W Trimpot is to provide a variable resistance value in a circuit, allowing for fine-tuning and adjustment of electronic signals. It consists of a rotating shaft connected to a resistive element, which changes the resistance value as the shaft is turned. This allows users to set a precise resistance value, enabling calibration and adjustment of circuit parameters.

200K 3296W Trimpot(Pack of 5) DocumentationThe 200K 3296W Trimpot is a high-precision, cermet-based trimmer potentiometer designed for precision applications. This pack of 5 trimpots is ideal for use in IoT projects requiring fine-tuned analog signal control. Here's a comprehensive overview of the component and code examples demonstrating its usage in various contexts.Component Specifications:Resistance: 200k
Power Rating: 0.25W
Tolerance: 20%
Linearity: 1%
Operating Temperature: -55C to 150C
Dimensions: 3.2mm x 3.2mm x 1.5mmPinout:The trimpot has three pins:1. CCW (Counter-Clockwise) Terminal: Connected to the wiper terminal when the trimpot is set to its minimum resistance value.
2. Wiper Terminal: The movable terminal that connects to the CCW or CW terminal, depending on the trimpot's setting.
3. CW (Clockwise) Terminal: Connected to the wiper terminal when the trimpot is set to its maximum resistance value.Code Examples:### Example 1: Analog Signal Attenuation (Arduino)In this example, we'll use the trimpot to attenuate an analog signal from a sensor, such as a photodiode, to adjust the sensitivity of the sensor.```c++
const int sensorPin = A0; // Photodiode connected to analog input 0
const int trimpotPin = A1; // Trimpot connected to analog input 1void setup() {
Serial.begin(9600);
}void loop() {
int sensorValue = analogRead(sensorPin);
int trimpotValue = analogRead(trimpotPin);
// Calculate the attenuation factor based on the trimpot's setting
float attenuation = trimpotValue / 1023.0;
// Attenuate the sensor signal
int attenuatedValue = sensorValue attenuation;
Serial.print("Sensor Value: ");
Serial.print(sensorValue);
Serial.print(" | Attenuated Value: ");
Serial.println(attenuatedValue);
delay(100);
}
```### Example 2: Voltage Divider (Raspberry Pi with Python)In this example, we'll use the trimpot as a voltage divider to generate a variable output voltage between 0V and 3.3V, which can be used to control a load or as an input to an analog-to-digital converter (ADC).```python
import RPi.GPIO as GPIO
import timeGPIO.setmode(GPIO.BCM)# Trimpot connected to GPIO 17 ( Pin 11 )
trimpot_pin = 17
GPIO.setup(trimpot_pin, GPIO.OUT)# Output pin connected to a load or ADC
output_pin = 23
GPIO.setup(output_pin, GPIO.OUT)try:
while True:
# Set the trimpot to a specific resistance value
trimpot_resistance = 100000 # ohms
# Calculate the output voltage based on the trimpot's setting
output_voltage = 3.3 (trimpot_resistance / (trimpot_resistance + 200000))
# Set the output pin to the calculated voltage
GPIO.output(output_pin, GPIO.HIGH if output_voltage > 1.65 else GPIO.LOW)
print("Output Voltage: {:.2f}V".format(output_voltage))
time.sleep(1)except KeyboardInterrupt:
GPIO.cleanup()
```Note: In both examples, the trimpot's output is assumed to be a linear representation of the resistance value. In practice, the trimpot's linearity may vary, and calibration may be necessary to achieve accurate results.
