How to Make LED Blinks?

In the last video, we saw how to make LEDs on and off. Now let’s see how to make it blink.

As shown in the video, write a program for blinking LED. Here, the delay is of 1 second. That means LED will stay on for a second and off for 1 second. Now connect your Arduino module. Upload your program. Check your COM port is appropriately selected.

After compiling, you will see your LED starts to blink.  Now for fast blinking, decrease the delay time. And upload it. Adjust delay time according to your requirements.

This way, you can make your LED blinks.

  • This Arduino project is very simple, but it can be used in many different ways. With this project, you can use the LED lights to act as a notification system or even a device that turns on when you enter a specific area of your home.
  • Arduino is an open source prototyping platform used for building interactive objects, primarily by hobbyists and professionals. It's easy to use and has been widely adopted by makers, artists, educators and engineers.

  • LED stands for light-emitting diode. A blinking light is a light that flickers on and off quickly, often with a pattern.
  • LEDs are solid-state devices that use semiconductor technology to emit visible light when electricity is applied across a p-n junction in the device.
  • The difference between an LED and a blinking light is the way they emit their light.

The purpose of LEDs blinking in IOT Arduino is to show the status of the device. For example, when the device is connected to a wireless network, it will blink its LED one time every second. This helps users know that the device is connected and working properly.

  • LEDs are getting more popular in the world of electronics. They are used to build light displays, sensors, and even robots.
  • The Arduino is a microcontroller that can be programmed to work with LEDs on it. It is an open-source platform that allows users to make their own circuits and create devices without any programming experience.

  • The Arduino is a small microcontroller board that allows users to build their own electronics projects. It is designed to be easily programmable and can be used for a variety of purposes. One of the many uses is to use it as a light sensor.
  • The Arduino has two built-in light sensors, one on each side of the board. These sensors are connected to two analog pins on the board and are capable of measuring light levels between 0 and 1023 in steps of 1023.
