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.

Oldest member of Nano family.

Enough interface for breadboard friendly applications

Heart – Atmega328 microcontroller

Clocked at a frequency of 16MHZ

Same functionalities as the Arduino Duemilanove.



22 digital pins.

8 analog pins.

A mini USB port.

First embedded micro-controller in the Nano series

 

Features:

High performance low power 8-bit processor.

Achieve up to 16 MIPS for MHZ clock frequency.

Flash memory – 32 KB of which 2 KB used by bootloader.

Internal SRAM – 2 KB

EEPROM – 1 KB

PWM Channels – 6

Power:



Mini – B USB Connection

6-20 Unregulated external power supply (Pin 30)

5V regulated external power supply (Pin 27)

 

Input / Output pins:

GPIO PIN stands for General Purpose Input output pin

22 – Digital (ON or OFF) GPIO PIN

8 – Analog – (Can take discrete values) GPIO PIN

6 – PWM Output

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...

2. Working Principle of Internet of Things

Consider reservation counters and banks for example: Typical computer system work on the principle, Input-->process-->output. In conventional system input is keyed in by human beings. The software algorithm running at the computing system, process the input data and produces an output. If people responsible are lethargic or lazy, often the speed and accuracy of the system is lost. But in IoT we do not have this issue. Inputs are replaced by relevant sensors. Hence possibility of human error can be eliminated to the great extent. Processing happens in cloud and returned to receiver end. Block diagram of the process-flow: In many IoT systems, sensors forward data via short-range wireless communication protocols such as Bluetooth, zigbee, wifi to the local computing system. Data gets pro-processed and sent to the central server or the cloud system. Analytics software system takes informed decisions at the cloud platform and will reach the receiver end device.  In few cases this ...
