1.5K Ohm Resistors (50 Pack)

Description

50PCS Resistor 1.5K ohm 1500 ohm 1/4w 1/4 w 5%

Tutorial: How to use Resistor 1.5K ohm

Resistors are fundamental components to limit the electrical current flow in a circuit. This 1,5kΩ resistor is ideal for Arduino and general electronics projects.

What you need

• Arduino
• multimeter

Steps

1. Check the resistance value of the component with the multimeter.
2. Connect the red end of the resistor to a digital pin on the Arduino (for example, D2).
3. Connect the other black end to the Arduino’s ground.
4. Write a simple sketch to read the value of the connected pin.
5. Upload the sketch to the Arduino and verify that everything works correctly.

Example code

void setup() {
  pinMode(2, OUTPUT);
}

void loop() {
  digitalWrite(2, HIGH);   
  delay(1000);              
  digitalWrite(2, LOW);    
  delay(1000);              
}

Mini project

Create a simple dimmer for an LED lamp using the 1.5kΩ resistor.

Common mistakes

• Connecting the wrong polarity of the resistor.
• Using a resistance value that is too low, which can burn out the Arduino.
• Not correctly verifying the resistance value with a multimeter.

Recommended accessories

• Arduino Uno
• LEDs and resistors of various values for lighting projects

Frequently asked questions

How can I control the temperature of my circuit using a resistor?
Use a temperature sensor like the DHT11 or LM35 with Arduino.

Can I use this resistor to protect my sensors?
Yes, but check the sensor’s datasheet for the correct resistor to use.
