Corona Virus Circuit

Our Corona Virus Detection Circuit consisted of four main parts, the alarm circuit, the logic circuit, the timing circuit, and the flip flops. The alarm circuit is was designed to play a siren when all three conditions for having "covid" are met, having a dry cough, low oxygen, and a temperature. The logic circuit was meant to either light a green, yellow or red LED depending on how many symptoms were exhibited and was responsible for activating the alarm when necessary. And last, the flip-flops and timing circuit were used to only test for symptoms periodically to avoid false positives. All together, these components created out Corona Virus Detection Circuit.

Alarm Circuit

In our project to build a coronavirus detection circuit, the alarm system is designed to activate when all three symptoms are detected. We encountered a few challenges like achieving the right amount of voltage because of its requirements. Specifically, we struggled to hear the alarm clearly because we had to find the right amount of batteries to provide a voltage within the acceptable range for the alarm's maximum and minimum voltage specifications. Ensuring the correct voltage was crucial for the alarm to function reliably, leading to some adjustments and adding resistors to balance the power supply appropriately.

Timing Circuit

In the process of building the timing circuit, we searched online for possible designs but due to a lack of the correct resistors, we had to make our own. By use of trial and error, we were able to find the proper resistors and could take one out, making the LED brighter.

Logic Circuit

Our logic circuit consisted of entirely AND and NOT gates. We planned this out in a smaller group using the whiteboard we had in the class to easily update and improve as we went. This logic circuit was simple and because it used so many of the same component it was compact on the breadboard. Although we struggled at first with figuring out how to use the AND and NOT chips in practice, after we figured that out the logic circuit came together quite quickly and worked with little issue.

Results: In the end, our final circuit did not work entirely as intended because of our failure to connect all the separate parts in a timely manner. Because we did not fully plan out our time beforehand we ran out and in the end each part worked separetely and not tegether. Next time we will be sure to plan our time out better to ensure time for troubleshooting and fixing.
