Why waste tons of money on sophisticated check-in systems for your dream startup! All you have to do is to get your creative juices flowing. The concept of IoT has opened up a plethora of ways by which you can bring life to the inanimate objects around you and get them talking and make them connect to the Internet. In this session you will learn how you can setup a Tessel(a popular IoT and robotics development platform) and connect the same with Salesforce consuming the Salesforce REST APIs to create an employee check-in system in no time and believe with very less code! You are sure to go back inspired by the simplicity of Tessel and the vast amount of use cases that you can think about by connecting Tessel and Salesforce. So join us to experience this match made in heaven - Tessel + Salesforce.

A plant starts talking!
“Hey! It’s time to water”.
Click a button and it’s
done!
Oops! Forgot to feed your
pet.
No wait! T’was done
already.
Home Automation
Forgot to turn OFF the
lights back at home ?!?

I wanna learn this. How do I get started ?
Multiple prototyping boards – CloudBit,
RaspberryPi, Arduino, Tessel
Start with easiest – CloudBit. You don’t need to be a
coder.
Beware! It’s very addictive. It’s creativity!
Joy you get when you start seeing a LED glowing.
Nothing short of ecstasy!
