Latest sketch and notes:

all hardware has been secured on the breadboard with my testbed arduino uno. so far concerns are back chatter — the power lines are not clean and I have isolated the main components of speaker and bluetooth transmitter/receiver on the board with some limiting resistors. my display values are unstable at startup after physical manipulation but can be returned to null after re-adjusting the connections. In particular, the pairing of the BT is reflected by an immediate 5 to 6 impedance drop on the soft pot lines, so for now, all testing begins only after pairing is complete.

the uno revision 3 should eliminate these issues as all power and ground lines are isolated on the board.

mac address for BT has been hard coded for tablet app and I have completed the bluetooth library integration in my app.

audio: currently utilizing TONE.h library for arduino to allow for software modulation of two tones simultaneously but this is not the final plan

all physical components are working without interference [other than power mentioned above]. testing has shown consistent performance over several hours.

Next Phase: will need to integrate BTLE beacon hardware and software

//when sending from serial be sure both NL and CR are on and baud rate matches
// ended up needing to use RX pin 0 and TX pin 1
// SR will be .25 seconds
