Description

50PCS 1.8 ohm 1/4w 1/4 w 5%

Tutorial: How to Use 1.8 Ohm Resistor

The 1.8 ohm resistor is a fundamental component for limiting electrical current in electronic circuits. It is ideal for beginners who are learning to design simple schematics.

What you need

• Arduino Uno
• Breadboard
• Jumper wires

Steps

1. Install the resistor between an input/output pin of the Arduino and the ground via a breadboard.
2. Connect the jumper wires to the ends of the resistor to connect it to the Arduino.
3. Write an Arduino sketch that reads the value of the resistor connected to an analog pin.
4. Check the voltage reading on the serial monitor of the Arduino IDE.

Example code

const int sensorPin = A0; // pin di connessione
int val;
void setup() {
  Serial.begin(9600);
}
void loop() {
  val = analogRead(sensorPin); 
  Serial.println(val);
}

Mini project

Design a simple circuit to measure the resistance and display the value on the serial monitor of the Arduino IDE.

Common mistakes

• Incorrect resistor connection.
• Voltage reading error.
• Impedance too low or high compared to the desired circuit.

Recommended accessories

• Breadboard
• Arduino Uno
• Jumper wires
