This puppy has a microcontroller + Wi-Fi onboard. The shields (and some newer Arduino devices) added the sorely needed internet connectivity support to enable the Arduinos to become true IoT devices.Įnter the ESP8266 MCU. As the company and user, the community grew so did the Arduino Shields and the devices themselves.
Its proliferation throughout the Maker community is a testament to exactly that. Most will agree that the Arduino was the first of its kind to be the simplest and cheapest microcontroller platform out there. While most IoT devices can be developed using powerful embedded computing devices such as the Raspberry Pi 4 most of our applications can be achieved through cheap, low-powered devices. To get the data to the cloud we need smart, reliable, and cheap internet-connected devices to assist us with the process. That data can then be analyzed and/or acted upon depending on different conditions that are set by the server that processes the data. Almost all embedded devices these days connect to the internet in one way or another to either collect or send data to the cloud. If you haven’t heard about the Internet of Things (IoT) movement by now you’ve probably been living under a rock.
