The Internet of Things (IoT)is the next most happening thing on the Internet at present. However, it is critical to comprehend the IoT’s precise nature and the reasons for the buzz it is generating in our society.
Connecting electronic devices (non-humans) to the internet is what the “internet of things” aims to do. Data analytics are used in these items. A tiny embedded system that can be as small as a postage stamp connected to the internet is capable enough of measuring the data.
What Is the IoT Learning Kit and What It Is Used For?
An IoTLearning kit consists of a Microcontroller Board , Sensors( Such as Temperature , Light, Distance, Moisture etc ) & Actuators(Such as Motor, Relay ,Valve etc) with circuitry hardware and Programming Code that is used to support microcontroller experimentation. Let us say you have a microcontroller that can perform a variety of amazing tasks, but in order to use it, you must first set up a collection of hardware and circuitry on your breadboard each time.
Smart engineers find this frustrating, especially when there are circuits that will be the same every time, such as power circuits. Briefly, development boards are built to facilitate prototyping and increase the efficiency of engineers.
