DIY your Arduino Board

Arduino is one of the most common tool in open source. Include me is in study in this projects.
So I am going to teach [How To Build An Arduino Board] by yourself and it's more cheaper.
(There are a lot of open source boards like Raspberry Pi、LinkIt and Newton to choose.)


Start 

The Data Sheet of CPU on board.
(This kind of datasheet can be found in IC company website)

 I made this draft after I read the guide in Arduino web.

And the material for building
Capacitor 104 x1 
22p capacitor x2 
10k resistor x1 (connection with Reset) 
16MHz quartz oscillator x1
  

Finish~ (I did so fast that I forgot to take picture on process...)

This is the adapter mod from TTL to USB

TTL (Transister-Transister-Logic)
Means using 0V-5V as the switch to operate the signal 0 and1.
