27K Ohm Resistors, 50 Pieces

Description

50PCS Resistor 27K ohm 27000 ohm 1/4w 1/4 w 5%

Tutorial: How to use Resistor 27K ohm

The 27kΩ resistor is a fundamental component to limit the flow of current in electronic circuits. Ideal for beginners and Arduino projects.

What you need

• Arduino Uno
• USB Cable
• Baseboard Kit

Steps

1. Connect the Arduino to the computer via USB cable.
2. Check the resistor on the datasheet to understand the precise value.
3. Connect the wires to the resistor and the Arduino according to your circuit diagram.
4. Load a simple sketch that reads the value of the resistor.
5. Monitor the output through the Arduino IDE serial console.

Example code

const int sensorPin = A0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  int val = analogRead(sensorPin);
  float voltage = (val / 1024.0) * 5.0;
  Serial.println(voltage);
}

Mini project

Create a light sensor using the resistor as part of the voltage divider to measure the light level in a room.

Common mistakes

• Connecting the wires to the circuit without first checking the resistor specifications.
• Using incorrect values in the Arduino code, not corresponding to the actual resistor value.
• Do not connect the ground (GND) between the circuit and the Arduino.

Recommended accessories

• Baseboard Kit
• USB Cable for Arduino Uno
• Light Sensors

Frequently asked questions

How do I check the resistor value?
Use a multimeter or check the product datasheet.

What is the maximum power this resistor can handle?
Check the datasheet, but generally for a 1/4w resistor the maximum power is 0.25W.
