continues to the rest of the program. As you keep pressing the Reset button, the odd/even
pattern continues, as does the program's alternation between the "Press/release Reset..."
and "Program running..." messages.
Example Program: TestResetButton.bs2
√ Enter, save, and download TestResetButton.bs2.
√ Verify that it displays the "Press/release reset button..." message and ends the
program.
√ Press/release the Reset button. Verify that the program displays the message
"Program running...", beeps 5 times, then displays the message "Done!".
√ Press/release the Reset button a second time.
√ Verify that the program behaves the same as it did when you first downloaded it.
√ Press/release the Reset button a third time, and verify that it behaves the same
way it did the first time you did it.
√ Keep repeating a few more times to make sure the odd/even pattern continues.
