XBee + Arduino Problem
Just found this on Digi website. "The XBee is a 3.3V only device, connecting 5V to any pin may damage the radio. If you had connected the XBee to a 5V microcontroller or power source, it's possible that the radio is damaged beyond repair". On this link, the last topic, knowledge.digi.com/articles/Knowledge_Base_Article/…. I really think that the XBee is gone. One way to avoid this problem is to get one of this regulated breakout board. http://www.hobbytronics.co.uk/xbee-explorer-reg. As it says in the description, it regulates ALL pins to 3.3V, making me believe that I needed to take care of that before making such a mistake. Hopefully this prevent someone from doing this mistake in the future. So, bye-bye XBee.
