Arduino Microcontrollers
Arduino boards are one of the famous microcontrollers used by students to professional level learners. It's available very cheap in the market. Arduino boards are mostly useful for IoT development purposes. If you are not aware about IoT just Read this article for more about IoT.
Who is Arduino?
Arduino is an Open-source platform for IoT developments. That community provides a lot of things to learn about Arduino microcontrollers and every year Arduino releases new microcontrollers with additional features . An Arduino having different microcontroller boards.
Just we see each other one by one.
Arduino microcontroller types
