Arduino String Case Change Functions Code

The String case change functions allow you to change the case of a String. They work just as their names imply. toUpperCase() changes the whole string to upper case characters, and toLowerCase() changes the whole String to lower case characters. Only the characters A to Z or a to z are affected.

Circuit

There is no circuit for this example, though your Arduino must be connected to your computer via USB.
