Raspberry Pi goes mobile, WP7 joins the ride

[Larsey]

Thought I could share with you people my latest project for the Pi

Read all about it at my blog, http://blog.fagerbakke.net/2012/8/13/ra ... -ride.aspx.

What I've done is removing the "brains" of a toy car and replaced it with a Pi connected to a motor controller. With the Pi connected to the wifi network I could connect and send commands to it.

Well done, cool project!

[Larsey]

Thank you!

As I mention in the blog this is my first project, I've only done a "turn on a LED"-type of project before. The Raspberry Pi platform is really a rich platform that allows you to do all kind of crazy stuff

But what I would want would be a distro leaning more towards this kind of work - arduino style in a way. I'm sure I could modify the existing distro, but I'm no Linux wizard

Very nice job Lars.

Looks great - can you list the motor controller used, and connections to the pi ?

Sure I can :

Motor controller is http://www.canakit.com/dual-motor-l298- ... k1122.html, it's quite expensive but gets the job done. It's also good for future projects since it very robust and versatile.

Each motor is controlled by 3 pins, for motor one it was IN1, IN2 and ENA. What you have to do is enable ENA with a "high" signal. A "low" signal is the pin turned off. IN1 and IN2 decides the direction of the motor. Enabling one makes the motor go one way, etc with the other.

I got my notes back home, but I just found 3 x 2 available pins (i think it was 10, 11, 12 and 20, 21, 22)

Well for a first project I'm impressed;)
Under Arch Linux Mono is quiet usable, so you can "share" code with you WP7 app;)

How do you go about it with the GPIO? You might be writing a wrapper or something to python, or is a feature already built in?

Some wrappers exists i.e.

Very tempting thanks. Ill look into it. In my case the python server (tcp server) was a very straight forward thing.

I realize that this is almost a year old at this point, but I'd love to see how you accessed your Pi via WP7 and the link no longer works. Please keep me updated!
