The next device is ready... ;) It is the TSL230R light sensor.
It prints out the Lux value every N seconds.
My code is based on this Blog entry. You could buy the sensor at Sparkfun where you will find the Datasheet too. Another place for code is here. There is provided a modified version of the link above.
Jehhaaaa... It is done!
My first Arduino device is born. Thanks to John! He learned me how to develop the driver for it. It is a DS1621 temperature sensor with 2-Wire (I²C) interface bus. And, YES! I have currently 17.5 degrees in my room.
I am impressed! The code will follow ASAP!
Since i am not lucky with the original LEGO NXT programmable brick because I need the programming environment provided by LEGO. Sure, there are nice implementations of alternative firmwares around the web but none of them are what I want. Sometimes they are using ugly languages like Java and sometimes the code for the firmware is not public available.
Now I have my solution. Move the LEGO NXT brick to your trash and build one by yourself using Arduino based boards.
Go, take a look! This is a really cool approach of a VPN implementation in just some few lines of code.
I have added a LEGO Mindstorms section to this site aiming on NXT development on the Linux platform. Go to the site here.
I will post Links to interesting projects and code there. If you have some interesting content for that site, please let me know!
