Introduction:
The Acme Fireplace Company has hired you to redesign the fireplace control circuit for their latest residential gas fireplace. The fireplace burner is equipped with four thermal sensors that output a logic (1) whenever a flame is present. These sensors are connected to the fireplace control circuit which outputs a (1) to the emergency cut-off valve to keep the gas flowing (i.e., a zero will turn the gas off).
The original design of the fireplace control circuit was quite simple. For the gas valve to remain on, all four sensors needed to output a logic (1). During field testing it was discovered that variations in gas pressure and humidity cause the thermal sensors to occasionally output a logic (0) even when a flame was present. This caused frequent unnecessary shut downs and constant customer dissatisfaction.
Conclusion:
Although this project was quite challenging and hard to come up with results, Max and I worked efficiently to get it done. We split the project up in two parts based on our strengths and learned about our weaknesses which helped us achieve our goal. I made the truth table and the K-mapping while Max created the circuits on Multi-sim as well as the TinkerCad circuit with some of my help.
