I am new to this forum as well as to Arduino and XBee. I have been trying to figure out how to take an analog DC voltage (from a device that measures CO2), send it by XBee Pro S1 to another XBee, process the data and send the original DC voltage to an LED volt meter as well as a serial monitor. Do I need a DAC to convert the serial data to an analog voltage? If so, how do I connect it and I need help with the code as I don't have a clue what functions and variables and commands to use. Please help! Any help at all would be appreciated
Suggest you work through a few of the code examples found on the internet first, as these provide a good intro
For example http://cs.smith.edu/dftwiki/index.php/Tutorial:_Arduino_and_XBee_Communication
Once you have understood the examples you can start to modify them to suit your purpose.
I did that. I went through several tutorials, but could not find one that approximated my needs. I was just hoping somebody could direct me to a tutorial more oriented to what I am looking for. Thanks anyway.
