180K Ohm 1/4W 5% Resistor, 50 Pieces

Description

50PCS Resistor 180K ohm 180000 ohm 1/4w 1/4 w 5%

Tutorial: How to use Resistor 180K ohm

Resistors are fundamental components to limit the flow of current in an electronic circuit. This 180K ohm resistor is ideal for Arduino projects where a high value resistor is needed to regulate voltage or create voltage dividers.

What you need

• Arduino Uno
• LED

Steps

1. Check the datasheet for the maximum power rating of the resistor (1/4w in this case).
2. Connect one end of the resistor to a digital pin on the Arduino.
3. Connect the other end of the resistor to one of the legs of the LED.
4. Connect the negative pole of the LED to the Arduino’s ground.
5. Download and save the test sketch on the Arduino.

Example code

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  digitalWrite(13, HIGH);   
  delay(1000);              
  digitalWrite(13, LOW);    
  delay(1000);              
}

Mini project

Create a simple circuit that turns an LED on and off with a 180K ohm resistor to limit the current.

Common mistakes

• Incorrect connection of the resistor or LED.
• Use of an inappropriate value resistor.
• LED polarity connected in reverse.

Recommended accessories

• Arduino Uno
• LED various colors
• Basic Kit for Arduino

Frequently asked questions

How is the value of the resistor calculated?
The value of the resistor is determined by the electronic circuit. For example, if you have an LED that requires 2V at 20mA, with a supply voltage of 5V, the resistance must be calculated as (5-2)/0.020 = 150 ohm.

How powerful is this resistor?
This resistor has a maximum power of 1/4 watt, check the datasheet for precise specifications.
