True/False.
Boolean data is one bit of information. True or false. It is common to use Booleans with control statements to determine the flow of a program. In this example, when the boolean value "x" is true, the program waits for 10 seconds then set the value "x" to false. After that "x" will be false forever turning ON the onboard LED permanently

    boolean x = true;

    void setup() {
      pinMode(48, OUTPUT);
    }

    void loop() {
      if( x == true ) {
        delay(10000);  // waits for 10 seconds
        x = false;
      } else {
        digitalWrite(48, HIGH);
      }
    }
