Conversion of data from char to int array after reading from UART in Arduino

The discussion addresses converting a subset of characters read from UART into integer variables in Arduino. The initial solution involves copying three characters into a String object and using the String.toInt() function for conversion. Further elaboration covers converting the resulting string to a float and formatting the output to display a specific number of decimal places. To remove trailing zeros after the decimal point, a method using String manipulation is proposed: converting the float to a String, checking for a decimal point, and iteratively removing trailing '0' characters from the end of the string. The explanation clarifies that string indices start at zero, so removing the last character involves subtracting one from the string length to access the correct index. The discussion references Arduino String class functions such as toInt() and String(val, decimalPlaces) for formatting numeric output.
