This time we will show you how to use the arduino outputs to turn on a led. For this we will explain the basic principle in addition to the connection scheme.

Although some sites on the Internet show you that it is possible to connect an LED directly to the digital or analog outputs of Arduino this is a bad practice and we will address this topic later, so we recommend you read the contents of this post completely.

This post can be used on other platforms than Arduino, even with a microncontroller without any type of board.

If you have decided to acquire an Arduino but you may have noticed that there is a great variety of them in the market and now you do not know which one to buy, this post is for you.

In this post we will let you know the capabilities of each Arduino model so you can make the best decision when buying one.

Arduino is part of physical programming, meaning that the programming we do will have interaction with the physical world. A clear example of this is to move motors, open doors, turn on spotlights, make LED sequences and use different types of sensors (Infrared, humidity, gas, ultrasound, etc ...).

Basically it was designed as an educational tool to be able to program the ATmega microcontroller, in this case the Atmega 328P-PU that belongs to the arduino uno.

Arduino is part of what we know as collective intelligence, which is achieved through the internet through the development of open source and open hardware, that is, all the hardware and software documentation of the card is released to the public so that anyone can develop, improve or extend it, including its development platform (Arduino IDE).
