arduino length of int
In C you can get the size of your array in bytes using sizeof(myarray); To get the number of elements you divide this by the size of a single element, like this: [font=monospace]int size = sizeof(myarray) / sizeof(int);[/font] but a better way is to alway,if (readString.length() >0) Serial.println(readString); //see what was received // expect a string like 123456789 with three data partts data1 = readString.substring(0, 3); //get the first three characters data2 = readString.substring(3, 6); //get the

On the Arduino Uno (and other ATmega based boards) an int stores a 16-bit (2-byte) value. This yields a range of -32,768 to 32,767 (minimum value of -2^15 and a maximum value of (2^15) - 1). On the Ar... https://www.arduino.cc String length() - Arduino
