In 1879, Thomas Edison invented the lamp and make the world brighter. What if a man
would say “I can flash all kind of lamps and leds without even touching them” to him. People
would look that man as a magician or witch. But what would your reaction today? In these
days, the technology companies are trying to use cloud technology to connect things to the
internet so that they can create free space in the company and they can use their things in –
whereever, whenever they want through an basic application. Connecting things to the cloud
technology we call that ‘Internet of things’. As you can understand from the name you can
connect anything to the internet literally.
Now there are a lot of carts that you can use for connecting to the internet such as
Arduino, Raspberry Pi, the BeagleBone etc. However, you must buy Wi-Fi module for
connection but with NodeMcu (ESP8266) you do not have to buy it. Also this cart is cheaper.
