Inspiration
- Before the pandemic, I would often work out at my local gym after my Grade 11 Physics Class, during lunch break
- It then closed so I tried to start a routine of calisthenics at home
- I managed to maintain the routine for a week before I naturally became lazy and gave up
- I had no motivation
- So during this hackathon, I decided to set out and find a way to bring motivation into physical activity
What it does
- You can challenge your friends to a workout battle (pushups, situps, squats, etc.)
- The FitBuddy Device on your wrist monitors your form and movement with its sensors
- It counts your reps and updates them in the app view
- You push yourself until either you or your opponent forfeit
- There is a ranking system (Bronze, Silver, Gold, Platinum, Diamond, Ultimate)
- Based on your wins, losses, form, and other variables, you are assigned a rank
- Keep pushing yourself and try to rank up!
- The app computes the motion numbers through a trained algorithm that gives you tips on how to improve your form
How I built it
iOS App
- XCode + Swift
- Firebase + Firestore
- Controls Entire Back-End Friends Network
- Real Time Synchronization
- User Profiles
- Friend Links
- Email and Password Control
- Form Improvement Tips
- Other Smaller Features
FitBuddy Device
- Arduino Nano
- Bluetooth LE Chip
- 3-Axis Accelerometer
- 3-Axis Gyroscope
- 3-Axis Magnetometer
- Pulse Sensor
- 18650 Lithium Battery + Recharge Circuit
Challenges I ran into
- Using Bluetooth with iOS and Swift, made me crazy haha
- Battery Circuit Voltage Dropout Every 5 seconds
- Creating Physical Enclosure
Accomplishments that I'm proud of
- The App, looks well done design-wise
- The Pairing Process, just tap the phone to the device!
- The Physical Device, doesn't look half bad!
What I learned
- How to use BLE with iOS + Arduino
- How to convert Acc+Gyro+Mag angles into an accurate angle reading
- How to use a pulse sensor
What's next for FitBuddy
- PCB Design with all components
- Clean up the app and release it to the app store
- Create a 3D Printed physical enclosure
- Create User Security Rules in Firebase
