Hello, I have two Arduinos currently set up, one to read RPM of an engine and one to read drivetrain rotational speed. I have them all functioning properly, however I find it frustrating that (using ArduinoCommander on my Android Tablet, connected via a BlueTooth Shield) I can only connect to one at a time to display information. I would like to be able to read these two on one single unit (another Arduino maybe?) and have that communicate with my android Tablet. I want to be able to datalog the information as well with whatever methodology I'm using to connect both Arduinos together. (I'm using 2 SD Shields, one to both Arduinos for this, I would rather just have to use one. The same goes for Bluetooth shields.)
Is this a feasible project, and if so how would I approach it? Or am I just being too hopeful?
