What is LED and How to implement it

What is LED and How to implement it?

Let’s see how we can code a basic program of LED that blinks it on and off.

Here, we are using Arduino UNO. You can define the function of pin and pin number in pinMode. Now what you want to perform on LED, that code will come in a void loop. Write code as per your specific requirements or as per video.

After writing code, go to tools and select Arduino UNO board. Then select COM as COM3. Upload your program. Before uploading, it will ask where you want to save it. Save it, and your program will start compiling. After that, it will upload.

See, your LED is ON at 13 number pin. To make it OFF, change your code accordingly.

FAQs

  • It is important to understand how to implement an LED in Arduino. The LED can be used for a variety of purposes such as displaying text, making patterns, and blinking.
  • In this tutorial, we will learn how to implement an LED in Arduino using the Arduino Uno board. We will also learn how to use the pinMode() function and digitalWrite() function.

RGB stands for red, green, and blue. RGBW stands for the same colors but with a white light. The difference between RGB and RGBW is that the latter is not a single color but a combination of colors.

  • Implementing LED in IOT Arduino offers a lot of benefits. It is easier to control the light and use it as an indicator. It can also provide feedback when there is a problem or the device is not functioning well.
  • The most significant benefit of using LED in IOT Arduino is that it provides better visibility and control over the light. This means that you will be able to see what your device is doing at all times, which can help with maintenance and troubleshooting.

  • LED is a type of semiconductor diode that emits light in the visible spectrum when an electric current flows through it.
  • IOT Arduino: In this project, we use LED to turn on and off the power supply to a DC motor. We used Arduino as our IOT platform to control the DC motor.

LEDs are light-emitting diodes that have many different types. There are three types of LEDs:

  • Common white LEDs
  • Blue LEDs
  • Red LEDs
  • Green LEDs
  • Yellow LEDs
  • RGB LEDS
