fired up an old pc and installed winxp  today>smiley-sad
Worked fine to upload sketches then so my arudino uno is working fine.
probably try ubuntu again later on.
For now i will play with my arudino smiley

i tried your tips on two diffrent pc's.
And i'm much closer now. Thx man !
one with opensuse 11.2 and one with opensuse 11.3

opensuse 11.3:
had to make a symlink to ttyS8 like this:
ln -s /dev/ttyACM0 /dev/ttyS8
was able tl select a com port then.
But i get this message:
Binary sketch size: 450 bytes (of a 32256 byte maximum)
avrdude: Yikes!  Invalid device signature.
         Double check connections and try again, or use -F to override
         this check.

opensuse 11.2:
no symlink needed, but i needed to rub arduino as root.
but i get this error:
avrdude: stk500_recv(): programmer is not responding

i tried flashing like in post #34

actualy twice but it still behaves like before, unable to upload anything to arduino uno.
checksum of Arduino-usbserial-uno.hex is 8e01ee236e70bbea43f7eb4e11c9688a

this is how i did it with messages from my system opensuse 11.3

sudo dfu-programmer at90usb82 erase

sudo dfu-programmer at90usb82 flash --debug 1 Arduino-usbserial-uno.hex
Validating...
4058 bytes used (99.07%)

sudo dfu-programmer at90usb82 reset

Hva med å koble pt100 elementet inn i en Wheatstone målebro ?
http://en.wikipedia.org/wiki/Wheatstone_bridge
Koblingen blir da slik 2, 3 eller 4 leder:
http://en.wikipedia.org/wiki/Resistance_thermometer

Tilpasser en driftspenning og motstandene burde det være mulig å få ut 0-5v for det temp området en ønsker.

Skal til med noe av det samme.
Regulere temperatur i akvarium med arudino uno og pt100.
