Hello everyone! Hopefully someone can help me.
I was using Arduino UNO with XBee PRO (and its shield) but now i want to make them both standalones.
i have no problem with Atmega328 as standalone, and i've already put a 3.3v regulator on my breadboard for the xbee
and i have the next connections:
ATMega328 -> XBee
pin Rx --> pin Tx
pin Tx --> pin Rx
Atmega is connected to 5v regulator and Xbee is conected to 3.3v (which is connected to the 5v regulator)
but it's not working, not even the TxLED from the XBee works.
Do i need more connections?
do i need to put a voltage divider in the Tx pin from Atmega so XBee would see a level of 3.3v?
thanks guys,
any help would be very much appreciated
