Android is OpenSource!
Look at this: Android running on OpenWrt. WTF? Thanks!
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... ;)
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.
