Questions tagged [iot]

QUESTIONS MUST BE PROGRAMMING RELATED.. Use a more specific tag for your question instead, e.g. [wifi], [bluetooth], [c], [arduino]

The Internet of Things (IoT) is a novel paradigm where many of the objects that surround us will be connected to the Internet, these objects can be Radio-Frequency IDentification (RFID) tags, sensors, actuators, mobile phones, etc. and through unique addressing scheme, are able to interact with each other and cooperate with their neighbors to reach common goals.

While programming questions about Internet of Things are on-topic here, other questions should be asked on the new Internet of Things Stack Exchange site.

enter image description here

If the question is not programming related then it may be on-topic at Raspberry Pi Stack Exchange, Internet of Things Stack Exchange or Unix & Linux Stack Exchange.
