AGENDA

• Intro to IoT

• Intro to Arduino Platform

• Hands-on programming using Arduino Platform

• Some Applications

Mobile

What is IoT?• In 2010, the global average of connected devices per

person was 1.84 • Taking only those people who use the Internet (around 2

billion in 2010), that figure becomes 6 devices per person

• “50 billion devices connected by 2020” – CISCO

4

What is IoT?

• Devices that connect to one another and interact using the internet.
