Component Documentation: 20K 3296W Trimpot (Pack of 5)OverviewThe 20K 3296W Trimpot is a variable resistor, also known as a trimpot or trimmer potentiometer, used to adjust and fine-tune electronic circuits. This component is a three-terminal device with a rotating shaft that allows for precise resistance adjustments. The 20K Ohm trimpot is a popular choice for various IoT applications, including sensor calibration, voltage dividers, and impedance matching.SpecificationsResistance: 20K Ohm
Power rating: 0.5W
Package: Through-hole, radial lead
Operating temperature: -40C to +125C
Dimensions: 9.5 x 5.5 x 5.5mmPinoutThe 20K 3296W Trimpot has three pins:Pin 1: Clockwise terminal (CW)
Pin 2: Center terminal (CT)
Pin 3: Counterclockwise terminal (CCW)Code Examples### Example 1: Voltage Divider Circuit with Trimpot (Arduino)In this example, we will use the 20K 3296W Trimpot to create a voltage divider circuit that outputs a variable voltage signal to an analog input pin on an Arduino board.Circuit:Connect Pin 1 (CW) to 5V
Connect Pin 2 (CT) to A0 (analog input pin) on the Arduino board
Connect Pin 3 (CCW) to GNDCode:
```c
const int sensorPin = A0; // analog input pinvoid setup() {
Serial.begin(9600);
}void loop() {
int sensorValue = analogRead(sensorPin);
float voltage = sensorValue (5.0 / 1023.0);
Serial.print("Voltage: ");
Serial.print(voltage);
Serial.println(" V");
delay(100);
}
```
### Example 2: Trimpot-controlled LED Dimmer (Raspberry Pi)In this example, we will use the 20K 3296W Trimpot to control the brightness of an LED connected to a Raspberry Pi's GPIO pin.Circuit:Connect Pin 1 (CW) to 3.3V
Connect Pin 2 (CT) to a 1K Ohm resistor, then to GPIO 17 (PWM output)
Connect Pin 3 (CCW) to GND
Connect the LED to GPIO 17 and GND (through a 1K Ohm resistor)Code:
```python
import RPi.GPIO as GPIO
import timeGPIO.setmode(GPIO.BCM)
GPIO.setup(17, GPIO.OUT)try:
while True:
trim_pot_value = GPIO.input(17) # read trimpot value
brightness = int(trim_pot_value (255.0 / 1023.0))
GPIO.PWM(17, 50).start(brightness) # set PWM duty cycle
time.sleep(0.01)
except KeyboardInterrupt:
GPIO.cleanup()
```
