| # Randomly Generated Challenge Alarm Clock Team Members: - Rithvik Kopparapu (rithvik9) - Allen Zhu (allenz2) - Zinovy Alecksandrovich (zinovya2) # Problem For college students, industry professionals, and people from all walks of life, alarms or other methods of waking up on time have become essential. Sleep is an essential need that no one wants to give up, yet there are numerous demands in our lives that take us away from the comfort of our beds. In order to stay on top of their schedules, people resort to various methods of alarms- setting many alarms all 2-3 minutes apart, downloading an app that forces them to take a picture, or using a smartwatch alarm. However, many times the human body automatically adjusts to the routine of a regular alarm, allowing people to snooze or turn off alarms in their sleep, turn off their phone, or getting used to the vibration of a smartwatch alarm. # Solution In order to solve this problem and force users to actually wake up in order to turn off their alarm, we wish to make an alarm clock with 4 different challenges using simple sensors (load cell, gyroscope, temperature, pedometer) to complete to turn it off- with the clock randomly picking which challenge needs to be completed every morning. Randomly picking between 4 different challenges every morning keeps the user on their toes, with minimal effort required from the user in order to set the alarm by having everything in one succinct device. # Solution Components ## Subsystem 1 - Alarm clock and speaker The first part of our solution is the physical alarm clock that we will be modifying to add our challenges. We wish to use a simple AA-powered alarm clock with a clear LCD display for the user to be able to easily program times in and use power efficiently. In order to inform the user what challenge is to be completed that morning, pressing the clock's snooze button will play an instruction on a separate speaker that we will add (i.e., "SHAKE CLOCK FOR ONE MINUTE"). ## Subsystem 2 - Challenge Deck with sensors The second part of our solution is our challenge deck with the associated sensors: Gyroscope sensor - MPU-9250 with built in gyroscope and accelerometer sensors. The challenge we want to incorporate here is to shake the clock for 1 minute, and we will use the data from the sensor to verify the shaking of the clock. Temperature sensor - TSYS03 temperature sensor. The challenge we want to incorporate here is to get up and put the clock in the fridge for 2 minutes while waiting there for the alarm to turn off. We will check to see if the clock holds a temperature below 40 degrees Fahrenheit (avg fridge temp is 37 degrees) for at least 1 minute, to consider the time it takes for the clock to cool. Pedometer sensor - MIKROE-3567 pedometer sensor. The challenge we want to incorporate here is to take get up and take 250 steps with the alarm clock. Load cell - SparkFun SEN-10245 load cell. The challenge we want to incorporate here is to apply an even and constant force for 3 minutes, in order to make it an inconvenient enough time to be unable to do it in your sleep. ## Subsystem 3 - Linkage to alarm clock To link all the sensors, we will be using a ATMEGA324PB microcontroller. To make the alarm clock stop ringing when the challenge is completed, we will generate the signal that is usually generated by the "stop alarm" button to the alarm. Once the challenge is completed, we will also use the previously mentioned speaker to give the user a simple audio feedback that they've completed the challenge, with a "ding" sound. # Criterion For Success Our criterion for success are as follows: 1) Each challenge needs to work appropriately and actually stop the alarm from ringing. 2) Challenges must successfully randomly switch every morning. 3) Alarm must only deploy one challenge at a time. |
