I just received my arduino mini 04 in the mail. There was some difficulty uploading code since this Arduino Mini 04 has the ATMega328. Apparently, the list of boards in the Arduino IDE doesn't have the specification for this new Mini. Fortunately, I found the solution in the forums. One needs to modify the boards.txt file. I uploaded the servo sweep example, and I'm hoping to start a new wearable computing project. I'll post pictures and videos as I have time to work on it.
