Hi, Arduino Mega1280, Arduino standard IDE, include string lib. To efficiently print out mixed data, I convert all data items into one concatenated string and send the string to the serial port. This works nicely, except that I can not control the output format for an individual item as I could do in single item Serial.print(value, HEX).Sorted by: 1. You can create a string result where you can concatenate your each iteration result and print that. You need to add spaces after each addition of words. So, append + " " to your result variable as well. def mod3 (ad): result = "" testAd =ad.split () for word in testAd: modAd = "" i = 0 for char in word: if i == 0: modAd += char ...

The answer by canadiancyborg is fine. However, it is always better to avoid using String objects if at all possible, because they use dynamic memory allocation, which carries some risk of memory fragmentation. Simple and safe: int answer = 42; Serial.print ("The answer is "); Serial.println (answer);

I have a Python script reading the data on the other side, if I could concatenate all the data from the sensors to send all at once will be much easy for me handle this data in Python. –Next it appends some text to the end of the string (not the end of the buffer) using strcat. The next to debug lines show the contents and the length (using strlen of the string. The contents is embedded in single quotes. Next the code converts the float value to string and appends to the current string (places it at the specified location).Syntax myString.concat (parameter) Parameters myString: a variable of type String. parameter: Allowed data types: String, string, char, byte, int, unsigned int, long, unsigned long, float, double, __FlashStringHelper ( F () macro).
