Iot Refers To The Connection of Everyday Objects To The Internet and To One Another

 

referss to the the connecti connection on of IoT refer everyday objects to the internet and to one another

 



It is the network of physical objects or things embedded with electroni elect ronics,sof cs,softwar tware,sen e,sensors, sors,and and network network connectivity which enables these objects to collect and exchange data.

What makes these smart?

These devices are all part of an emerging category called the Internet of things.

Raspbian, installed via NOOBS

 



consists of both a physical programmable circuit board (often referred to as a microcontroller) microcontroller) and a piece of software of software,, or IDE (Integrated Development Environment) that runs on your computer, used to write and upload computer code to the physical board.

 

The Arduino, is a microcon microcontroller troller,, which whic h means it excels at controlling small devices like sensors, motors, and lights.  Ardui Arduino no is best best used for projec projects ts like like building building a wake-up light, motion detector alarm, or even a small robot. 

 

The Raspberry Pi, isn’t a microcontroller, and isn’t made for controlling sensors and other things like that.  It’s an entire computer, with its own operating system, and is intended to be used as one 

 





The Arduino’s power supply requirements are very simple; you can plug it into your computer or a battery pack, and it will start running code immediately. If the power is disconnected, it will stop; there’s there’s no need to run a shut-down process. The Raspberry Pi,more on the other hand, because it has a full-featured computing system in place, should be shut down like a regular computer, and can be damaged by power cuts.

 

The Raspberry Pi comes ready to be connected to the internet; it has a built-in built -in ethe et hern rnet et port port..  The Arduino, on the other hand, doesn’t have any built-in capability for connectivity. If you want to connect it to the internet, 

you’ll need to add extra piece of port hardware hardw are that includes incluan des an an ethernet ethe rnet

 

The Arduino Arduino comes comes with 32 32 KB of onboard onboard storage, which is just enough to store the code that provides instructions for its current program. You can’t use this storage for apps, videos, photos, or anything else.  The Raspberry Pi, on the other hand, doesn’t 
