Support Adafruit

Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!). For those who want to get a project off the ground without programming - Adafruit IO offers a No-Code interface for building IoT electronics projects using WipperSnapper, our open-source IoT firmware. Support Adafruit’s open-source development by subscribing to Adafruit IO Plus, the upgraded, all-systems-go version of the Adafruit IO service.
