This is the truth table for our circuit. The G,Y,R and B represent the colors green, yellow and red and the sound of the buzzer, which reacts to the flip flop of the circuit. C,O,T stand for cough, oxygen and temperature, (oxygen intake measures runny nose, in response to breathing difficultly). This is how the circuit can tell whether or not someone has the Covid-19 symptoms and how many they have. Cough, fever and runny nose, all have varying severity and this truth table helps determine the impact of each symptom in relation to one another. A runny nose is no big deal, allegories and even routine cleaning however, a runny nose and a fever, is cause for concern. The bot detects and responds to these with varying degrees of severity. It should be noted that as noted in all combinations must be considered. While there is only 1 option to produce either a green signal or the buzzer, there are 3 options that produce the yellow signal and 3 that produce the red signal.
