Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You are tasked with designing a system using the 8051 where a button press initiates a timer to generate periodic beeps. How would you implement this?

💡 Hint: Think about the use of ISRs and how the initial interrupt services this task.

Challenge 2 Hard

Create a simulation where an external interrupt toggles two different LEDs based on alternating button presses. Describe your approach in implementing this.

💡 Hint: Consider how to manage state with a global variable.
