  • I’m not sure what I’m doing wrong. (n00b warning).

    I’ve got the following project working with my uno ( 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.


  • I’m a big n00b, but what resistor values should i use for this with an arduino or attiny chip?
