So you want toconnect your stuff to the internet!

Good News is

Bad news is

Unlike open source software, open source hardware still need money

More skills is needed

Replicator? Not there yet.

While this won’t happen.

This is a very real danger(the house not the girl)

Commercialization means

Help is available!

Online resource for learning

Lets start

Microcontroller!

● Read input from sensor● Output to somewhere.● programmable

Why not a computer

● GPIO Limit○ Smaller voltage○ Fewer pins

● Did I tell you it sucked at reading analog

How about cell phone?

● You can’t easily add more sensor easily● To add sensor to phone you

○ a microcontroller to ○ USB interface (ftdi)○ Sensor○ Maybe battery

Many available

● Arduino● raspberry pi● pcduino● beaglebone● PIC ● etc

Arduino….

● This is the one I work on a lot, Sorry :-(

The arduino

These are arduino too!

Specification is released

You can make it on a breadboard!

Have a nice community

Easy to use software

Easy to experiment

What not so cool

● Not the most powerful around● Only limited to C/C++● Some of the recent design not so open

Example project

org/wiki/Arduino_Mega_Pololu_Shield● etc

Lets Talk Component

Where to get components!

Online shop! Go to the earlier slide

p.s pasar road is good too, the experience varies from people to people

You can get premade component

There is also shield to make prototyping easy

Some Pre-assembled one.

To use pre-assembled component

1. Find if someone already use it!2. If not start here. Read data sheet3. Understand what you have4. Find out any extra component needed5. Now connect it

The internet part

● You essentially have interface to the world● Provide

○ API to read/write○ used by device○ UI to explore data

● 2 main one○ Xively○ thingspeak, it’s open source!

Xively

This is my project

Get the software part here

● https://gist.github.com/sweemeng/9663343● https://xively.com/feeds/1068165020

What next

● Go on and explore!● Make stuff, anything!

○ Except killer robot that attack human● I did not do a lot of stuff. But there is a lot

more people done!●

Idea

● Maybe we can map out pollution in KL ;-)● A christmas light that light up with more
