Why do you constrain the values for the Y servo to 1500, 2100 and the X to 800, 1900?
To keep wiring safe, power cable to board coming up from accumulators. It also good idea to put separate switch for servo motors, to prevent accidents during start up., or use a "delay switch"
So could i use the following to convert it to degrees?
Code:
rot = map(srvoPosn[y], 1500, 2100, 0, 180);
. Yes, srvoPosn will hold integrated value of the angle, if you keep same hardware set-up - motors moving with platform. Angle would depends on base positioning. May be not very accurate, depends on servo specification non-linearity etc.
if the debug just prints "n" does it mean it is not correctly receiving audio?
Mark "n" easy distinguish in digits column, compare to "0" , if "n" printed - there is no data.
