SpotLight

Inspiration

We wanted to build a device that would allow us to safely manuever our rooms at night without having the need to switch on the light or a flashlight and waking up our sleeping roommate.

What it does

Motion sensors track our movement and position and shine a dim light in that direction. App allows us to switch the app on and off and mark dead zones which teach the device not to shine a light in certain areas under any circumstances.

How we built it

Lucas: Project lead, Hardware, used motion sensors, LEDs and photo receptors. Handled the electrical component of the hack. Claire: developed code in Java for connecting Bluetooth with the Android Studio code. Aarohi: Designed the UI of the app, designed algorithms which allow the GUIs to function. Katie: Used SolidWorks to model the device and 3D print the parts.

Created by

I primarily worked on developing the Android app used to switch on/off and calibrate the device. I focused on designing the UI and GUI elements and implementing action listeners as well as incorporating Bluetooth to communicate with the arduino.

Aarohi Palkar
I worked on developing the mobile android app that utilizes Bluetooth to connect to arduino. Primarily, I worked on coding the Bluetooth portion. This was my first time making a mobile application and my first time writing a project in Java. I also helped during assembly.

Claire Chen
I came up with the idea, lead the team, and worked on the electronics aspects of the project. I worked on the Arduino code, integration of sensors, and bluetooth communication.

Lucas Moiseyev
I designed the structural parts of our project using SolidWorks. I also printed those parts using a mix of CubePros and MakerBots. Before the parts finished printing, I worked on building a model out of cardboard. I did most of the assembling work once the electronic work was completed.
