STEP 7: We want the timer to count down by 1 every second.

• Go to and drag Interval Event into your program. Delete the .turn_left() command.
• Change the integer in the event handler to 1. Now the interval will run once every 1 second.
• Go to and drag Global Variable inside the interval event so it has a ···· in front of it.
• Change the name of the global variable to timer.
