I’m not sure what I’m doing wrong. (n00b warning).
I’ve got the following project working with my uno (http://blog.makezine.com/projects/make-34/the-dryer-messenger/) but when connecting the wall wart dc jack to the pro mini I keep blowing it up. I connect the positive from the jack to “raw”, then the negative to the ground on the mini board. I get a red light on the pro mini blinking fast and also the wall wart has a red light that begins to blink.
I’m not sure what I"m doing wrong. but the board powers up fine with a FTDI friend.
Thoughts?
