Hi everyone,
Will you please let me know if the attached diagram will work? my intention is to use the same buttons to control the sketch but at the same time to let Xbee know they were pressed.
My project description can be found here on Hackaday.io
I attached also the Fritzing file in archive.
The Arduino sketch can be found here on Arduino forum.
Please advice,

Arduino mini 3v3 with Xbee.zip (10.8 KB)
I use 2 batteries for 3.3V modules, or 3 batteries for 5V modules, to power the modules directly (bypassing regulators). 9V block batteries have low capacity, half of which is only dissipated in the on-board regulator.
Make sure that either both boards operate at the same voltage, or add protection resistors to the digital inputs, when the pullup resistors are connected to a higher voltage.
Hi Dr.Diettrich,
By the tech. specs. of the both boards the voltage should be 3.3v but since I am not an electronics knowledge guy I asked for help and the design review.
Xbee regulated board specs and Arduino Mini Pro 3.3v spec
Will the battery last long enough under this circumstances: 8h / day one LED on and every 25 min a button press (meaning Xbee will send signal). I think the biggest power consumption will be on the Xbee side, right?
Thanks!
The specs are not really helpful to answering your questions. Find out yourself.
Hi Diettrich,
as you said 'Find out youself" well it worked!, the project can be found on Hackaday.io under WiFi Timer system title.
Thank you all!
