Introduction
Introduction
Combining electrical engineering, computer engineering, and bioengineering, a masterpiece was formed that amazed the world. Slowly climbing the ladder of knowledge, we went from simple circuits with resistors in series, to bringing in capacitors. Alarms constantly sounded throughout the room, driving the minds of many to the brink of mental retardation. With constant trials and switching from dim LEDs to bright LEDs, the minds of many bright humans combined and worked together to reach the finishing point. Throughout the process, batteries have overheated, and flip flops have fried. Although the stress pressing on the young minds was large, but with firm will and determination, everything was completed in time and minds relaxed, with everyone hanging a smile on their faces.
Design Process
Design Process
Starting with the alarm, we took up an entire class time through countless trials and errors in order to have the sound emit from the alarm. The other group in the room was able to complete the alarm before us, and the abonoimable screeching sound that came out of the alarm greatly impared our ability to concentrate on the tasks at hand.
We finished the alarm the day after, for which we started on the timer at this time. The timer took a smaller amount of time to complete, as the website for finding the time intervals made the resistances easy to modify. Once we got the hang of it, we were able to modify the fluctuation of time based on what kind of resistor we wanted to use.
The hard part about the lab was putting everything together. After they were being connected via wires, the alarm became inaudible, and the LEDs did not want to cooperate. When we made the alarm work, the timer would not, and it was a very annoying process to constantly shift wires around.
In the process of putting together the entire lab into one setup, one of the batteries overheated and started to bubble, making a sizzling sound, and the power has to be disconnected, therefore temporarily discontinuing the entire lab.
In the end, because the logic gate received too much voltage, it fried. It was funny.

Series Circuit
Series Circuit
The successful series circuit experiment involved connecting the battery to the circuit, resulting in the illumination of the green light.
Alarm Circuit
Alarm Circuit
The successful experiment with the alarm circuit occurred when the alarm, connected to the battery through the circuits, produced a sound.
Green LED
Green LED
The green LED represents triple false or three zeros, shows our first step to success.
Timing Circuit
Timing Circuit
The timing circuit is like a timer, when the green light shines, the times is up. When the light does not shine, then it would show when the timer checks. The light turning off symbolizes that the detector is currently in cooldown mode and will check again after a fixed time period.
Circuit Lab
Circuit Lab
Not only did we conduct real-life circuit experiments, but we also carried out online simulations for the lab. The success of these experiments was achieved by effectively running the circuits. This circuit took more than two days to finally complete.
