How to turn on several LEDs

How to light multiple LEDs?

In this article, we will show you how to light multiple LEDs at the same time using some simple tools and basic knowledge about electrical circuits. If you've ever wondered how to get multiple LEDs to light up at once, you're in the right place. You will learn the correct connections and components necessary to achieve this goal. Once you master this technique, you can create your own lighting setups with multiple LEDs. Let's get started!

Step by step -- How to light several LEDs?

  • Step 1: Gather the necessary materials: several LEDs, resistors, cables, and an Arduino development board.
  • Step 2: Connect the Arduino development board to your computer via a USB cable.
  • Step 3: Open the Arduino IDE program on your computer.
  • Step 4: In the Arduino IDE program, select the type of board you are using (for example, Arduino Uno) and the port the board is connected to.
  • Step 5: Connect the LEDs to the Arduino development board. Connect the positive terminal (anode) of each LED to a digital output pin on the board and connect the negative terminal (cathode) of each LED to a resistor, and then connect the other end of the resistor to ground (GND) on the plate.
  • Step 6: Write the code to turn on the LEDs in the Arduino IDE program. Use the digitalWrite() function to set the digital pins connected to the LEDs as output and the digitalWrite(pin, HIGH) function to turn on the LEDs.
  • Step 7: Compile and upload the code to the Arduino development board.
  • Step 8: Verify that the LEDs light up when running the program on the Arduino development board.
