RobertC, quick question, if I was to use the TX pin to the Arduino, will the buzzer still sound? I am using this board for a “temporary” school project, so just for this project it is ok for now. I will use the board for another project later, but I was curious if I could connect this board to an Arduino and it transmit the data to the Arduino Uno ok, and if some one might have a schematic that showed it worked would be very helpful as well.
