Tutorial: How to use 30K ohm Resistor

The 30k ohm resistor is a fundamental component for regulating electrical current in circuits. This tutorial will guide you on how to use it correctly.

What you need

• Arduino Uno
• Jumper wire

Steps

1. 1. Identify the 30k ohm resistor in your kit.
2. 2. Connect one end of the resistor to the input pin of the Arduino and the other end to ground (GND).
3. 3. Download the provided Arduino code.
4. 4. Upload the sketch to your Arduino Uno.
5. 5. Verify the correct functioning of the circuit with a multimeter or serial monitor.

Example code

int ledPin = 13;
void setup() {
pinMode(ledPin, OUTPUT);
}

void loop() {
analogWrite(ledPin, 255); // Usa la resistenza per regolare il valore di analogWrite.
delay(1000);
analogWrite(ledPin, 0);
delay(1000);
}

Mini project
