Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Modify the LED blinking code to create a pattern where the LED blinks 3 times quickly then stays off for 1 second.

💡 Hint: Think about how you can use nested loops for timing the quick blinks.

Challenge 2 Hard

How would you implement a more precise timing mechanism without using a software delay? Consider using timers.

💡 Hint: Look into how to configure timers for interrupt-driven programming.
