greetings 2 part question
project scope = 2 arduinos (1 uno which i own) and 2 xbees. the question is would i be limiting my funfactor by purchasing a 2nd uno? or should i go with a different model? im not real clear on the differences, or if there is any big differences other than pin(s) offered. im probably going to have sensor information flowing between the 2, maybe some motor/servo control. maybe even a remote to control a little vehicle to chase my dogs around. i dont want to buy remote controlled vehicle im retired and im bored and i want to build all the stuff. not looking for code, just really great/fun way of using all this stuff together to maximize stimulation to my lil brain.
part 2. ive got my eye on these XBee Pro 60mW Wire Antenna - Series 1 (802.15.4) - WRL-08742 - SparkFun Electronics, so the interface between these xbees and the arduinos would be? would also like to dual use that interface to configure said xbees via usb, and/or use one connected to laptop, plus arduino to arduino. xbee explorer the answer? or cheaper way? i can solder well, would these be part of my solution? Breakout Board for XBee Module - BOB-08276 - SparkFun Electronics
thx in advance, you know reading about the products for hours tends to blur and confuse, especially since i dont have the parts in hand to mess with. i welcome some advice, insight, even what your favorite way of doing this is. thanks much.
