The Two Towers

This project was a simplified reference to a scene in Lord Of The Rings when multiple towers on top of mountains are lit up in order to warn people across the land of impending danger.

Supplies: Paper, 2 LED's, iron thread, an Adafruit Circuit Playground, 2 magnets, one piece of felt, copper tape, battery, pencil.

The original design would have included more LED's in parallel, however, due to limited time, I was only able to put two LED's in the final design. The design is essentially two LED's in parallel with a switch.

The initial design that I created was made with copper tape in series. Unfortunately, due to some sort of physical bug, I could not get this design to work. However, if I had a better power source, I surely would have chosen to have this schematic instead, because I think that it would work better theoretically to have it so that all of the lights turn on only if they are all able to.

Because the first design with the copper tape did not seem to work, I tried a second time with a parallel circuit since the battery theoretically would be able to handle it better. However, we ran out of time before I was able to finish this design. My final design would be based off of this one.

I would have liked to have made this design more complicated but we ran out of time and I had an appointment outside of class I needed to get to. However, luckily this one worked. It was a simple parallel circuit with two LED's and a ground circuit and a power circuit to connect to.

Now I will argue all day long that this technically is a switch, as it is a break in the circuit that turns on and off the entire project. However, if I were to design this product for a real life situation (or if I had more time in class), I would have made a much better design that included the switch on the outside for ease of use. This switch is not impressive and I am aware of that, but it still is a switch.

It is a simple drawing of two light sources on top of mountains "communicating" with each other. If I were to have more time, I would have liked to make this design much more complex with a range of mountains that included a switch on the outside of the product.
