Good day,
I wanted to share my project, I am stuck in what is for me a big wall at the moment for me, I have tried different approaches and fail and wanted to see if a different approach should be taken in consideration or if what I am trying to achieve is feasible.
Basically trying to pass analog signal X&Y from a joystick from xbee to xbee and then render it in Arduino. I have tried to include the analog signal of the Y axe and I fail all the time.
Any assistance would be appreciated in completing this project which I would like to share once done.
Thank You
My settings:
Transmitter xbee series 1 settings
ATRE
ATMY1234
ATDL5678
ATDH0
ATID0
ATD02
ATIR64
ATWR
Receiver xbee series 1 settings:
ATRE
ATMY5678
ATDL1234
ATDH0
ATID0
ATWR
where I am at so far
