In the world model of ubiquitous computing, aka, “Things that think,” significant physical objects have intelligence, temporary storage, sensing components, and often form computing networks. These wireless sensor networks are usually pretty sophisticated: One popular networking protocol is Zigbee, based on the IEEE 802.15.4 standard…
However, I’m seeing another approach to communications for these proliferating objects that are just so eager to talk with something: Twitter feeds. You’re probably familiar with Twitter, the micro-blogging platform that constrains posters to a brusque 140-character limit. It’s a simple yet robust method for posting 140 characters in a stream out to the world for online monitoring. Less well-known is that Twitter has a search function that’s much closer to monitoring information in real-time than Google’s search, and no wonder, since Twitter’s searchable content is a fraction of the size of the HTML pages Google attempts to keep up to date…
Just a quick note to add – Twitter is a cheap/easy/free SMS gateway, super simple for notification services for devices – it’s also fun for folks to build projects like Tweet-a-watt and show the results to their friends (or anyone else).
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
