After the confusion of dealing with many wires, I rearranged the wires successfully. However, I realized that there was an issue with the logic flow as it assumes that emotions are discrete. To account for this, I decided to also add a pressure sensor to capture the intensity of the emotion. My final design enforces the employees to indicate how they feel and how strong that emotion is so that they could indicate the end of their working hours. From the backend, the management will see on the console a row that has values of 0 and 1 along with the time, which they would decode to understand how the employee felt and ensure that they completed their hours.
