Parameters

labels	Array to store labels corresponding to each sensor reading
readings	Array to store sensor readings as floating point values
array_ix	Array index to label and readings
which_ultrasonic	Which ultrasonic to take reading with: 0: First ultrasonic sensor 1: Second ultrasonic sensor 2: Senix toughsonic sensor
take_average	Whether to take average or not 0: Take first valid reading 1: Take average of valid readings
ultrasonic_loops	Number of readings taken on each call.
max_size	Maximum size of label and reading arrays (number of entries)

Returns

(*array_ix) + number of entries filled
