After some months of studies, the blog need to improve.
So I'm migrating to wordpress, and my first project will be start on it.
In this new blog I'm going to improve and learn all the knowledge needed to build a drone.
I'll try to do all the steps from zero.
By the moment it's the most simple design, a terrestrial vehicle with wheels (it could have legs, or jump , crawl, so it's no so trivial )
The idea of this vehicle it's to be a base of test and to improve, so it will be as simple as possible.
I'll try to use almost information I've searched on internet about similar things, and modify to accommodate to my project, like engines, batteries, gear, etc.
But for start, I'm going to design my own vehicle
(arduino + cubieboard ) ^imagination = everything you can do
I hope to see you in my new blog, I'm doing this for the community to share and improve our knowledge.
Thanks for all and I'll see you at http://doingDrones.wordPress.com
And I'm thinking about this other board Udoo

Exercise 3º Drive a DC motor
The simplest and not for a real use.Till now, I was communicating from the arduino to the cubieboard, this is quite important, but now, I've to send the information from the cubieboard to the arduino.
For example, I send the amount of milliseconds that the dc-motor must be running.
The circuit is on of the most simplest
You can find all the information here (very good tutorials)
I took this schema
and here is the circuit, I had to change some values about resistor, transistor, etc. Cause I've to reutilizes some old components
cu -s 115200 -l /dev/ttyS0
Obvious it can be do better, but just is to show the idea.
