Calling the elevator by email using wifi, Arduinos and a relay, they’ve built a full triggering and sensoring system. From Alice Wonders:
It all started with a simple idea: call the elevator by email. Today, email is much more of a corporate tool and no one else uses it as they did before. Remember when we shared videos, pictures and links by email? Not anymore. Facebook messages and timeline, sms, Whatsapp and others, are what is trending now to share our lives with our online peers.
After a quick search and many laughs, we decided to put the idea to work. To use email to call the elevator seemed to give a new function to something increasingly without functionality. Even that the whole idea was not very practical, we had to make it. But, we barely knew how.
By the way, this is a text full of technical jargons and most of them are baby talk to Sheldon. If they do not make any sense to you, skip it and stick with the video.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
