    Open Sesame: Control a Garage Door with Twilio Studio, Sync and a WiFi Module FhIw5NYCdTJX95W5P1zGtr2ssNCxuIwiE7VOgLimf4UO-0uFTT2M17UYUhFm-lHmhlYIX1-5e4yedpMvUcF7CwimiOIkkVBzs766Uhcvbfnu8DzCmu5YfGTK1Vu4qGUXtzNTSII4

    Communication between the worlds of humans and machines doesn’t need to be apocalyptically hard or prohibitively expensive. In this project, we are going to build a voice call operated garage door opener with an ESP8266 dev board and a relay. In order to stitch all the parts together, we will use our visual workflow builder Studio and Sync for IoT.

    We use Twilio Sync for IoT and Studio in this project, which are currently in Developer Preview. Sign up for the Sync for IoT preview and the Twilio Studio preview before you begin.

    Gather the Garage Door Hardware

    Our final flow will use an ESP8266 to link your garage door to a communications flow via Sync for IoT. Here’s what you’ll need:

    Alternatively, if you are good at soldering …

    Build a Serverless Remote-Controlled Lego Robot with Twilio Sync and Runtime TbwNN7JmDjzlPNZnayxnpGAT3a2YfpoR-urTR-vJSw5m8vFfTSjo4o2FQpBNVu907TPzuG5tRHnN-e4x5vGE1a1jK0Ws19EWpD-cP6t9K9M2doH7OT6bt1Kk1inDGs07tj_OaOTk

    The world of Internet connected devices is exploding and there are billions of things already online. Today we’ll skip the smart thermostats and fridges and move straight to programmable droids.

    Building Your Droid

    We use Twilio Sync for IoT in this project, which is currently in Developer Preview. Sign up for the preview, and the team will get you on-boarded.

    To keep this project entertaining, repurposable, and extensible, we are going to use the Lego Mindstorms EV3 kit, a popular platform for basic robotics builds. We’ll build an internet controlled lego robot with a real-time web dashboard and even demo touch control.

    Key ingredients include:

    • Lego Mindstorms EV3 kit
    • A compatible WiFi USB dongle (one from this list; we used the Edimax EW-7811UN.)
    • 2GB (or larger) MicroSD card to install EV3dev image
    • Spare AA batteries

    Assemble the Hardware

    Follow Lego’s online instructions to assemble the EV3D4 droid. Once …
