Hi guys, I have 1x Arduino Uno, 1x GSM shield and 1x Xbee shield as shown in picture below.
My intention is to send SMS and to transmit the information wirelessly but how do I connect the GSM shield to the Xbee shield via wires?
What are the power supplies Xbee shield needs to function properly?
Well, you can have a try of crowtail kit at http://www.elecrow.com/crowtail-c-611.html that including crowtail base shield and functional shield that are suitable to the beginner. It is easy to use and can save your time and money.
I've just deleted two copies of this topic.
