Tutorial: How to use 8.2K ohm Resistor

Resistors are fundamental components in any electronic project, they are used to limit the flow of electrical current through a circuit. This 8.2k ohm resistor is ideal for beginners who are learning to work with Arduino.

What you need

• Arduino
• test kit
• jumper wire

Steps

1. Check the resistance on the electronic multimeter.
2. Connect one end of the resistor to digital pin 2 on the Arduino.
3. Connect the other end to ground (GND).
4. Upload the test sketch to the Arduino.
5. Observe the behavior of the circuit with the resistor inserted.

Example code

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

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

Mini project

Create a simple PWM lighting circuit using the resistor to control the potentiometer arm and vary the brightness of an LED.

Common mistakes

• Connect the resistor to the wrong pin.
• Reverse the polarity of the resistor.
• Use it in a circuit that requires a different resistance.
• Do not check the resistance with a multimeter.

Recommended accessories

• Electronic test kit
• Potentiometer 10k ohm
• LEDs various colors
• Jumper wires
