i try to load the ledarray_test make and it gives me the error message " avrdude: error: selected device is not supported by programmer: m168 make: *** [ledarray-upload] Error 1

Hi topklassent,

Could you post up a screenshot of the error message, just so we can see the whole context in which the error is occurring. Just by your snippet it seems to me you probably added an extra line break or removed a necessary piece of your makefile when editing your COM port.

topklassent. try removing that / before COM1!

Just use COM1 in your makefile.

If that does not work please post your make file, use the Indent Selection as Code Block so that we can read it.

Hi topklassent,

Did you change the -c directive from the one we provide in the LED Array kit makefiles? I believe you want -c avr109.
