Schematic Diagrams
This set up consisted of one battery that connects to the logic unit. The logic unit is uses the information from our truth table decide which path the signal should take. We then put all the different ways the risks could be presented from our truth table and the logic equations we put in our truth table into a series of AND gates. Since they all go into an OR gate for each AND, the one that works, would lead to whether or not the led light was turned on. This was also the situation for the alarm. We first built this circuit using the digital d flip flop. With this set up we could not get voltage to go into our led lights. Furthermore, the way our switches were set up, it did not make a difference whether the switch was turned on or not.
This is our second set up for the circuit. In this set up, we were able to get voltage in every area. We also reconfigured the switches so that turning the switches on and off would change whether it went through the NOT gate (meaning the input was negated) or not (meaning the input was present). We also added a digital T flip flop. This flip flop allowed us to get the voltages. We used the same plan for the AND and OR gates from above, but this time was able to execute it correctly.
After we got feed back from Darin regarding our circuit design, we decided that we had to change a lot of our circuit. We created a logic unit starting with a single battery in order to better coordinate which way the current should go based on the input data. We used a series of AND and OR Gates to help us utilize the logic from the truth table to identify the right symptoms. Then from the logic unit, we used flip switches in order to direct the current to the correct part of the circuit.We used 3 different switch flips in order to correctly identify which light needs to turn on based on the input from the logic unit. From the flip switches, we also have connected to the alarms as well as the timer. We still have an issue with simulating the circuit because we can not figure out how to work the timers to get it to run. We get voltage for the correct light right up to the flip switch and do not know how to to change the timing to get the flip flop to turn on to get the light to show up.
