Here is our final design.

This is the graph of the timing simulation with two parameters ticked down. The red led should be the only led receiving voltage

Some of our other failed designs can be seen here

Here, we tried to base the 1s and 0s off of set values rather than an actual circuit. This didn't work since there was no power source.

The design on the left had a logic system that worked and was similar to the most successful design, but the alarm didn't have a power source and the timer was nonexistent. The design on the right took a wholly different approach. It triggered the LEDs and alarms by short circuiting other wires. Though, this didn't work due to the current always passing through all the wires rather than the ones we wanted.
