11K Ohm Resistors (50-Pack)

Description

50PCS 11K ohm 11000 ohm 1/4w 1/4 w 5%

Tutorial: How to use 11K ohm Resistor

Resistors are fundamental to regulate the electric current in a circuit. This 11K ohm resistor is ideal for Arduino projects where limiting the current or creating a voltage divider is necessary.

What you need

• Arduino Uno
• Led
• Connectors

Steps

1. Check the datasheet for the specifications of the 11K ohm resistor.
2. Connect the led to the digital pin of the Arduino through the resistor to limit the current.
3. Write an Arduino sketch that turns the led on and off with a two-second rhythm.
4. Check the datasheet to see if additional components such as capacitors or parallel resistors are needed.
5. Test the circuit to ensure everything works correctly.

Example code

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

void loop() {
  digitalWrite(13, HIGH);   
  delay(2000);               
  digitalWrite(13, LOW);    
  delay(2000);               
}

Mini project

Create a simple illuminated clock that turns the led on and off based on the time of day.

Common mistakes

• Using a resistor of too low or too high value.
• Connect the LED directly to the voltage without protection.
• Do not test the circuit before final use.

Recommended accessories

• Arduino Uno
• Set of LEDs in various colors
• Basic Kit for Arduino
