# 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).

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.

## 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.

Featured Project

**Problem:** When working out at home, without a trainer, it’s hard to maintain good form. Working out without good form over time can lead to injury and strain.

**Solution:** A mat to use during at-home workouts that will give feedback on your form while you're performing a variety of bodyweight exercises (multiple pushup variations, squats, lunges,) by analyzing pressure distributions and placement.

**Solution Components:**

**Subsystem 1: Mat**

- This will be built using Velostat.

- The mat will receive pressure inputs from the user.

- Velostat is able to measure pressure because it is a piezoresistive material and the more it is compressed the lower the resistance becomes. By tracking pressure distribution it will be able to analyze certain aspects of the form and provide feedback.

- Additionally, it can assist in tracking reps for certain exercises.

- The mat would also use an ultrasonic range sensor. This would be used to track reps for exercises, such as pushups and squats, where the pressure placement on the mat may not change making it difficult for the pressure sensors to track.

- The mat will not be big enough to put both feet and hands on it. Instead when you are doing pushups you would just be putting your hands on it

**Subsystem 2: Power**

- Use a portable battery back to power the mat and data transmitter subsystems.

**Subsystem 3: Data transmitter**

- Information collected from the pressure sensors in the mat will be sent to the mobile app via Bluetooth. The data will be sent to the user’s phone so that we can help the user see if the exercise is being performed safely and correctly.

**Subsystem 4: Mobile App**

- When the user first gets the mat they will be asked to perform all the supported exercises and put it their height and weight in order to calibrate the mat.

- This is where the user would build their circuit of exercises and see feedback on their performance.

- How pressure will indicate good/bad form: in the case of squats, there would be two nonzero pressure readings and if the readings are not identical then we know the user is putting too much weight on one side. This indicates bad form. We will use similar comparisons for other moves

- The most important functions of this subsystem are to store the calibration data, give the user the ability to look at their performances, build out exercise circuits and set/get reminders to work out

**Criterion for Success**

- User Interface is clear and easy to use.

- Be able to accurately and consistently track the repetitions of each exercise.

- Sensors provide data that is detailed/accurate enough to create beneficial feedback for the user

**Challenges**

- Designing a circuit using velostat will be challenging because there are limited resources available that provide instruction on how to use it.

- We must also design a custom PCB that is able to store the sensor readings and transmit the data to the phone.
