Arduino Projects 1/3: an IOT Gauge with Arduino Yun and IFTTT

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.

Material

• Arduino Uno, or Arduino Yun
• Ethernet shield,
• Ethernet cable,
• Servo motor, https://www.adafruit.com/products/155
• Jumper wires, https://www.adafruit.com/products/759
• 3 x M3 nuts & bolts
• 4 mm plywood
• USB cable

Tools

• Laser-cutter at your local Fab Lab, https://www.fablabs.io/map
• Hot-glue or wood glue
• Android or iOS phone

Downloads

• IoT Gauge design files, http://www.thingiverse.com/thing:453788
• Yaler Arduino library, YalerEthernetServer.zip (for the Uno)
• Arduino Uno code, IoTGaugeWebService.ino
• Arduino Yun code, IoTGaugeMailboxApi.ino

Here is the 5 steps guide to make the Gauge by yourselves.
