Hi there. I'm a rookie when it comes to these projects, but I'm looking to build a simple device that uses Zigbee to talk to a server. I've never used either an arduino nor zigbee before, but think that I can figure it out when I have the parts. The first step though is understanding what I need to purchase. There are a lot of options. Can someone please point me to what is necessary in terms of the arduino, the zigbee module, adapters, and any sensors? Thanks much.
