Building a Prototype

Starting our Prototype

Once we completed the design phase and had a general idea on what we were going to build for our prototype, we each branched off into our own parts that we were supposed to do. We started off with basics like tinkering with wiring, code, and put our parts that needed to be 3D printed into the queue to be printed. We will also start to make our formal presentation and our trifold for the afternoon and evening showcases.

Troubleshooting

LED panels

We first chose to use LED panels for our project but this ended up being too ambitious for the time we had because we weren't familiar with them.

LED code

We had to work through the code and constantly test and revise it to ensure that the patterns playing were correct.

Circuitry

This is part of the circuitry for our prototype. The full circuit is composed of:

6 red and 6 blue LEDs
12 330 ohm resistors
1 photoresistor
1 10k ohm resistor
1 keypad
1 breadboard
1 Arduino Mega
wires

Final prototype

Outside view

On the outside of the cabinet the only component visible is the keypad that disables the alarm. On the back side of the cabinet there's a hole to thread the Arduino and webcam cords to the laptop.

Inside view

On the inside of the cabinet the parts visible are: the LED circuit, webcam, programmable speaker, and the wires of the keypad.
