Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider a heating system that uses an OR gate to monitor temperatures from multiple rooms. If room A exceeds 70°F or room B exceeds 75°F, the heater should turn on. Create a truth table for this setup.

💡 Hint: Map out the conditions where the heater should activate.

Challenge 2 Hard

Design a system with three sensors: smoke, temperature, and CO2 levels, using OR logic to activate an alarm system. What would be your approach?

💡 Hint: Think about how integrating more inputs can enhance safety measures.
