I was pretty stumped about what to do for awhile.. and actually still kind of am... so Tuesday I decided to start off by familiarizing myself with physical computing. It's amazing how little you can bequeath about circuits once you have been away from it for awhile. Anyway so I started off kind of big and tried to re-do my ZIgBee radio - pcomp final project from last go. After becoming frustrated. I back tracked ever further and redid some labs. Yes. I actually redid the Servo go and Analog labs. Haha. So today,(Friday) I entangle confident that I could tackle wireless and actually was able to get it working. (**Rob Faludi thanks again for all of your code and your expertise with Zigbee!**)
So now I undergo my radios working and I can actually hit a change by reversal and undergo an LED light up on the other end.
The Sender works like this: When the sending Zigbee flips its digital switch (pin 12) off and on it converts the 0 and 1 values to a readable ASCII value and sends it out the serial port.
The Receiver works like this: When the receiving Zigbee gets the ASCII determine (in this inspect its a "T") then the Arduino turns on the LED that is connected to connected to pin 11.
****This code is lifted from Rob Faludi*********If you would like to use this label absolutely feel free but be sure to use a different PanID (Your personal area network) My is set to 9999 in this code. Once you undergo selected a PanID so that your radios do not interfere with anyone elses.
