IOT is a concept provides a link for an object (sensors, lamps, …Etc) or a systems as HVAC or lighting systems to the Internet. It extends the connectivity of the Internet beyond PCs, tablets and smart phones to others devices which are not considered smart.
Briefly, we assign an IP to things to communicate with them either for control or monitoring. In this instance, I used my android tablet to control 3 LEDs attached to raspberry pi GPIOs via Sockets using Java.
Of causer this is a simple prototype but you can build a cool things on it.
Each Friday is PiDay here at Adafruit! Be sure to check out our posts, tutorials and new Raspberry Pi related products. Adafruit has the largest and best selection of Raspberry Pi accessories and all the code & tutorials to get you up and running in no time!
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.
