The best thing about this arrangement is that no other changes in the program have to be
made. The program will still function normally, and you can display each bit value as
before.
Your Turn - Working with the Sensors Byte
Here is an alternate Initialization and Main Routine you can try to see how a byte can
show you different patterns of bits (1s and 0s). A
builds a display heading to label each bit in the sensors variable, with a reference to the
sensor whose status that bit stores. Then a
updates the value of the

Save TestAllSensorsYourTurn.bs2 as SensorsWithFlagsByte.bs2.
Modify the variable declarations as explained in this activity.
Test the program and verify that it still works the same.
