Features

• Type: 3296W-104 (100K)
• High Precision
• Total Resistance: check the datasheet

What it is for

The 3296W-104 potentiometers can be used to create a dimmer for an LED lamp, adjust the intensity of an electronic signal through an NPN transistor, or in any other project that requires current modulation. They are compatible with Arduino and other microcontrollers.

Tutorial: How to use 100KΩ Precision Potentiometer

The 3296W-104 (100K) potentiometer is a high-precision electronic component ideal for adjusting the resistive value in analog circuits. It is particularly useful for beginner makers who want to control the functions of their project with greater accuracy.

What you need

• Arduino Uno
• Head connections

Steps

1. Connect the central output of the potentiometer to an analog pin on the Arduino (for example A0).
2. Connect the two ends of the potentiometer to the positive and negative power supply voltages.
3. Open the Arduino IDE software and load a sketch that reads from the analog pin connected to the potentiometer.
4. Check the readings on the serial monitor of the IDE to ensure that the output changes when the potentiometer knob is adjusted.

Example code

int val = 0;
void setup() {
Serial.begin(9600);
}

void loop() {
val = analogRead(A0); // Legge il valore dal pin A0
Serial.println(val); // Invia il valore al monitor seriale
}

Mini project

Create an LED lamp dimmer using this potentiometer. Connect the resistor to an NPN transistor and adjust the light intensity with the potentiometer knob.

Common mistakes

• Connect the middle pin to a digital pin instead of an analog pin.
• Fail to connect the two ends of the potentiometer correctly to positive and negative voltage.
• Overload the Arduino output pin with too much current from the resistor.
• Fail to check the readings on the serial monitor to verify the circuit’s operation.

Recommended accessories

• Arduino Uno
• LED
• 220Ω Resistor
• NPN Transistor
