i want to println to the serial port a series of numbers seperated by a comma
eg "1,2,3,4,1.1234567890"
when i try to concatenate the numbers together into a string it fails on the last number (1.1234567890)
is says "conversion from 'float' to 'const String' is ambiguous"
is it possible to create a string that is a mixture of integers and floating numbers ?
