ARDUINO + NXT

Hi guys. I would like to ask you one question. Does somebody has any idea if there is some possibility how to use NXT servo motors with arduino without buying any of that expensive shields???

Thank you so much for alllll answeres!!

What does Google say?

I found one good project and is also posted here in forum:
http://forum.arduino.cc/index.php/topic,8739.0.html
he wrote library too but I am completelly confused from it. I cant find there header file or I dont know how it works
Here is his library:

Maybe you,which are better in this can understand it and explain me little.

Than I found lot of articles with nxtmmx but is really expensive so I am searching for some other possibilities. If you know some I am thankfull to all of them!!!

Nobady??

Try this

I found the missing header & cpp files. Converted to Arduino 1.0+ format so they compile (I cannot test them though) and attached here.

Thank you so much as soon as I will be able I will try it if it works. I just have to find out how to connect l293d to nxt motor any ideas?

There are several ideas and project floating around about Arduino and NXT if you want to take a look at what I found:

These look like really neat projects. I'm not sure what your skill level or familiarity with these products are, but I hope this helps.

Thank you for your respons!
I found really interesting this project:

there are also planes for make this board which I find iteresting.

This projects are interesting problem which i have with them is, they are using there nxtmmx which is really expensive!

The second one i found that they are using arduino as Slave and in my project I am using arduino as master. I expect there is no possiblity how to use arduino as slave and master in the same time or?
