Tomas Amberg shared with us the link to an Instructable he published on how to build a Web-enabled, Arduino-based IoT Gauge with a REST API, and connect it to the IFTTT mash-up platform, via the Yaler.net relay service he founded.
The cool thing about this project is the connection with the Maker Channel of IFTTT which supports custom Webhooks, to integrate DIY IoT projects:
Inspired by WhereDial, a DIY Internet of Things classic, the IoT Gauge shows the current location of its owner. A bit like the Weasley Clock in Harry Potter. The design and code of the IoT Gauge is generic and could be used as well to display e.g. weather conditions. The logic resides in the Cloud, the gauge is just a servo with an API.
