It accepts various data types such as integers, floating-point numbers. Each one would then have it's own I/O pin number, state, and also importantly for your purpose, a printable name. Description Prints data to the serial port as human-readable ASCII text. print() function is used to send data as human-readable text over the UART interface. Numbers and text will be seperated by space. Something like 'var 255' and arduino should write integer 255 to variable 'var'. I would like to send to arduino with serial monitor strings with variables. I want my program to be more readable than it is now just printing out values. Serial.print (variable, HEX) will print the value of the variable in HEX, for instance and you can also include \t, and \r in strings to give a tab, newline and carriage return respectively. x is taking on multiple values in my program. You can influence the output of Serial.print a small amount by using parameters after the value to be printed. You would think this would be simple but I can't find a proper answer anywhere. Then you instantiate an object from that class for each button you have. Need help, read serial string with variable. Where I want 'x' to be printed as characters on my serial monitor and where the other x is a variable. Generally, the answer to your requirement (assuming it is really required), is to make an OO class of button objects, with all the data items associated with a button contained in the class. Is this an experiment, or is it supposed to do something? There is no debounce logic in your program, to handle switch contact bounce.
