Sunlight Alarm

Window Shade Alarm Log
Presentation 1

Proposal

Overview

Our goal is to create an apparatus that opens your window shades automatically in the morning, providing a more pleasant way to wake up than a loud alarm. Our apparatus would use a stepper motor to open the shades paired with an Arduino and Dual Step Motor Shield. The stimuli to open the shades would be based on time as inputted by the user using a keypad attached to the Arduino. A Raspberry Pi would fetch the current weather and time and send it to the Arduino to be displayed on LCDs, informing the user of the time and weather.

Team Members

• Sam Chai
• Cole Fitzsimmons
• Arnob Dam
• Andrew O'Sullivan (TA)

Objectives

• Build frame and shade
• Program Raspberry Pi to send time and weather to Arduino
  • Use NTP and Wunderground API
  • Program Arduino to accept time and weather from Raspberry Pi
• Program Arduino to accept input from user
• Program Arduino to control motors
• 3D print pieces to attach blind to shade
• Attach motors to frame/shade
  • up/down pull-string

Challenges

• Learn how to use SolidWorks
  • We will use SolidWords to 3D print gears, clamps and other physical parts for the opening/closing function of our device
• Learn how to program Raspberry Pi
  • We are using Raspberry Pi instead of Arduino because we will need Raspberry Pi's capability to access the internet. Through the internet, we will have access to and display both time and weather
