7. What is Arduino Nano

The Arduino Nano is a microcontroller.

The Arduino Nano is Arduino’s classic breadboard friendly designed board with smallest dimensions.

The Arduino Nano comes with pin headers that allow for an easy attachment onto a breadboard and features a mini-B USB connector.

It is an intelligent development board designed for building faster prototypes with the smallest dimension.

3. History of IoT

Brief History: The term ‘Internet of Things’ was coined in 1999 by the computer scientist Kevin Ashton in the presentation he made while working at Procter & Gamble. Ashton proposed putting radio-frequency identification (RFID) chips on products to track them through a supply chain is essential to communicate between people and things and things themselves. Wanting to bring Radio Frequency to the attention of P&G‘s senior management, Ashton called this presentation as ‘Internet of Things’ to incorporate the cool new trend of 1999 the internet. Though Ashton mentioned it in 1999, the first appliance was a coke machine invented in the early 1980s at the Carnegie Melon University. A group of students from the university created a way to get their campus Coca-Cola vending machine to report on its contents through a network in order to save them the trek if the machine was out of Coke. They installed micro-switches into the machine to report on how many Coke cans were a...

4. What are IoT devices?

Description: When it comes to IoT, internet is used to send, receive or communicate information. And in each case, the gadget that was connected to the internet wasn’t a computer, tablet or mobile but an object (a thing). They are internet connected devices, hence each of them has a unique IP address and the devices r ange in complexity from Autonomous vehicle to simple sensors. Any object in the physical world can be transferred into an IoT device if it can be connected to the internet to be controlled or communicate information. IoT devices are generally expected to have an internet connection and that communication with the network independently of human action. Idea of IoT: Rather than having a small number of very powerful computing devices in life such as laptop, tablet, music player, phone you mi ght have a larger number of devices which are perhaps less powerful such as umbrella, bracelet, mirror, fridge, shoes and water bottles. For this reason, a pc, a smartphone a ...

6.4 Ohm's Law

Ohm's Law: Describes the relationship between Voltage , Resistance , Current i.e., Voltage = (Current) X (Resistance). It was proposed by George Simon Ohm. Ohm's law states that "The current through a conductor between two points is directly proportional to the voltage across the two points" . The law only holds true if the provided temperature and the other physical factors remain constant. V= IR An electrical circuit is a closed loop that connects various electrical elements. We can also analyze the electrical circuits in terms of Voltage, Current and Resistance. The equation V = IR, can be rearranged to find any one of the three quantities (Voltage, Resistance, Current) given the other two such as: 1. V = IR 2. I = V/R 3. R = V/I For Example: In the circuit above Voltage from the battery and Ohm from the resistor has been given. To compute the current flowing through the circuit, the formula is: I = V/R (or) Current = Voltage / Resistance I = 10/100 I ...
