ORIGINAL MESSAGE: Hi,
I need some help with a project. I basically want to wirelessly communicate between my computer and an Arduino UNO, over a maximum range of about 30 metres. What is the best way of doing this?
This is what I have so far: - Get two XBee modules. - Connect one of them to my computer using a USB to Serial Base Unit (https://www.sparkfun.com/products/8687 ) - Connect the other to an Arduino using a 'Wireless SD Shield' or 'XBee Shield' (Which should I use?) - Use Serial to communicate XBee to XBee
Will that option work, and is it the best way of doing this? And also, does XBee only communicate to XBee or can I only use one XBee to communicate to my computer?
EDIT: I also found this APC220 for $40 with 2 modules, 2 antennae, 1 TTL-USB Convertor. http://www.dfrobot.com/index.php?route=product/product&product_id=57#.U4i36nJdVok Will that work? It looks cheaper and includes everything.
