program again. The time after that, it does not halt the program, and so on. So the
program utilizes your Board of Education's Reset button as an on/off toggle button.
Below is an example that uses the code block in a different way. Instead of halting or
allowing the program to continue, the
program is run, then executed the second time the program is run (after pressing and
releasing the Reset button). It is then skipped the next time and executed again the time
after that. The net effect is that the program either counts down and jumps straight to the
Record_Data
whether your board's Reset button has been pressed/released an odd or even number of
times.
Example Program: EepromDataStorageWithReset.bs2
This program demonstrates how to use an address in EEPROM to control the way the
program behaves, depending on whether the program has been run or re-run an odd or
even number of times. The number of times the program has been run will be controlled
by the Reset button after download. If the Reset button has been pressed/released an
even number of times, the program starts with the menu from the previous activity. If it
has been pressed/released an odd number of times, it performs a countdown, and then
calls the
