A String is a sequence of characters.

For the Calliope mini, ASCII character codes 32 to 126 are supported; letters, digits, punctuation marks, and a few symbols. All other character codes appear as a ? on the LED screen.

Create a string variable

let greeting = "Hello";

To create a variable that holds a string:

  1. Click Variables (in the Block drawer).

  2. Type a name for your new string variable by clicking the down arrow, then click New Variable. Then type the variable name “salutation”

  3. Drag a string block on the right side of the operator.

  4. Click "Hello" and then type a string like hello.

Your code should look something like this:

let greeting = "Hello";
