Added german Ardunio IRC channel

I have added #arduino-de to Freenode in hope there will be people from Germany meeting up there.

German language preferred but no must!

Please join to create a german IRC community for Arduino... ;)

Arduino Relays

Yesterday evening I have build a small relays for switching high voltage lines with my Arduino. It uses the "Blink" example and switches on for 10 seconds then switches off for 10 seconds. I have used this document to get my work done.

Arduino TSL230R

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.

Arduino DS1621

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!
