Tutorial: How to use 5mm YELLOW LED

5 mm YELLOW LEDs are ideal for illuminating small electronic projects, such as status indicators or visual signals. They are useful for both beginners and more experienced makers.

What you need

• Arduino Uno
• Appropriate resistor
• Jumper wire

Steps

1. 1. Check the 5mm YELLOW LED electrical voltage on the datasheet.
2. 2. Select a resistor based on the power supply voltage and the maximum current value of the LED to avoid damage.
3. 3. Connect the cathode (short pin) of the LED to GND of the Arduino using a jumper wire.
4. 4. Connect the anode (long pin) of the LED to a digital pin of the Arduino through the previously selected resistor.
5. 5. Insert the Arduino sketch to turn on the LED.
6. 6. Download and upload the program to the Arduino.
7. 7. Check that the LED turns on when the digital pin is set to HIGH.
8. 8. Try changing the values in the code to control the brightness or add a timer.

Example code

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

void loop() {
digitalWrite(13, HIGH);   
 delay(1000);               // Attende 1 secondo
 digitalWrite(13, LOW);    
 delay(1000);               // Attende 1 secondo
}

Mini project

Create a simple illuminated clock using yellow LEDs and a network of resistors. Configure the LEDs to light up sequentially or simultaneously.

Common mistakes

• Using a resistor that is too small, which can damage the LED.
• Connecting the anode to GND instead of a digital pin of the Arduino.
• Do not check the LED voltage on the datasheet.
• Try to power the LED directly from the battery without a resistor.

Recommended accessories

• 220 Ohm resistor
• Jumper wire kit
• Arduino Uno R3
• 3D printed case for Arduino

Frequently asked questions

Which digital pin on the Arduino should I use?
You can use any digital pin, but remember to connect it to the resistor and the LED.

What is the lifespan of a 5mm yellow LED?
Check the datasheet for the precise value. Generally, LEDs can last for years if used correctly.
