| # Smart Curtains Team Members: Jack Davenport (johndd2) Vinay Konda (konda3) Max Mauschbaugh (maxjm2) # Problem Oftentimes an alarm clock is not enough to wake people up in the morning, and when they do wake people up it is an immediate and shocking way to start your day. I know I'm not the only one who gets shivers whenever they hear the iPhone alarm ring at any point throughout the day. We want to create a product that will complement an alarm clock to make the wake up process more effective and enjoyable. # Solution We want to make smart curtains that automatically open in the morning to assist an alarm clock. The curtains should open at a certain time in the morning based on what the user sets it to and should be able to sync up with an alarm clock by connecting via wifi. We believe that waking up to natural sunlight is the healthiest and most enjoyable way of getting up in the morning, and hope we can create a system that lets us do so. # Solution Components ## Curtain Movement Subsystem For the movement of the curtain itself, we will use a motor connected to two strings that will wrap around the furthest curtain ring on either side. One string will be used to open the curtains and another to close them (similar to the opening and closing of elevator doors). For the motor and its controller these should be sufficient: [Motor](https://www.amazon.com/Greartisan-Electric-Reduction-Centric-Diameter/dp/B072R5G5GR?th=1), [Motor Controller](https://www.amazon.com/Greartisan-Controller-Variable-Regulator-Governor/dp/B07H8ZJSFQ?th=1). For the thread we’ll use something durable like this: [Cotton Thread.](https://www.amazon.com/Colors-Macram%C3%A9-Natural-Knitting-Wedding/dp/B07KCZXKYX/ref=sr_1_15?keywords=cotton%2Bthread%2B1%2Bmm&qid=1675135320&refinements=p_36%3A2638326011%2Cp_76%3A2638115011&rnid=2638113011&rps=1&s=arts-crafts&sr=1-15&th=1) We will 3d print parts for the motor shaft to be able to fit and pull the two strings. When opening and closing, our motor will coil the two strings around the shaft in opposite ways, increasing slack of one string and decreasing the slack of the other. This will allow for the motor to rotate one way to open the blinds, and rotate the opposite way to close them. ## Processing Subsystem Our microcontroller will connect to our WiFi module to receive information about alarm times and more, which the microcontroller will then process. Something like this will work for the WiFi module: [ESP8266](https://www.sparkfun.com/products/17146). The PCB’s open and close state for the curtains depend on the alarm information sent via WiFi. In addition, we will have a physical button for manually changing the PCB’s open and close state. Something like this should work: [Button](https://www.superbrightleds.com/more-led-lights-and-fixtures/installation-supplies/switches-dimmers/rocker-pushbutton-remote-switches/mini-on-off-toggle-switch-wired-mini-on-off-toggle-switch-wired) ## Power Subsystem In order to power the pcb, motor, and other components of the system we will be using a rechargeable battery. # Criterion For Success - Able to reliably open and close curtains using one motor and a string. - Accurately opens/closes with respect to alarm using wifi. - Manually open/close blinds based on toggle of a physical button. |
