no, ive used 2 different atmegas to make sure one wasnt damaged. the power light is on - on the adapter. also, i have 2 of these adapters im trying, just in case one is damaged. i usually order stuff in twos. to me this should be a simple thing lol, very confused. the breadboard setup is minimal, atmega, xtal, xtal caps, thats it. (the entire circuit is a receiver for weatherstation. but since it didnt work from get go, im working with stripped breadboard. also, on an uno without sdcard this works fine. im building it on a breadboard to stay with the 3.3v because i want to add the sdcard, but i cant even get it to spit out "hello world" to the pc lol.
