Components Required to Build the Project

  1. Breadboard (Want to know what is breadboard and how it works? check this link out )
  2. Battery
  3. 1 LED
  4. 330 Ohms Resistor (Confused with colour code and not sure which one is 330 ohms? check this video out to see how to measure the resistance using the multimeter)
  5. 1 Switch
  6. Some jumper wires

Tips

Tip 1 : Finding the Polarity of LED:

If you look closely at an LED, you’ll see that one leg is longer than the other.

✅ The longer leg is the positive side (called anode).
❌ The shorter leg is the negative side (called cathode).

This helps us know which way to connect the LED so it works properly! 💡😊

Tip 2: Choosing the Resistor Value for LED:

A resistor is very important! ⚡

If you connect a battery directly to an LED without a resistor, the LED will burn out instantly. 🔥💡

To keep the LED safe, we must use a resistor in series. This controls the amount of electricity flowing through the LED so it doesn’t get too much power. 😊

To find out which resistor to use with an LED, we need to know how much power the LED needs.

🔴 LEDs use about 20mA of current and need 2-3V to light up. This is called Forward Voltage (Vf).

Different LED colors may need more or less power depending on their type. That’s why we use a resistor to make sure the LED gets the right amount of power and doesn’t burn out!
