What are my options on where to connect the arduino/flow sensors?
I have a kegbot server installed on a VM Linux box. I know I can hook the arduino to my nexus 7 with an OTG cable and have it report the flow data back to the server. However my tablet is temperamental at best, so I would rather have a setup that was not dependent on the tablet. I will use the tablet as a front end but if it is locked up or not charged or being used for something else I still want to monitor the beer flow.
I know I can use a raspberry pi and have the arduino hook directly to it. I would need to buy a PI and reinstall the server on it instead of my VM.
Can the arduino hook directly to the computer (assuming I can make the VM see the serial port correctly)? I would need to make sure the computer is somewhat close to the Kegerator.
Can the photon report data directly back to the server? I would need to buy a photon, which I want to play around with one anyway.
