Title of your project

Tiltris (It's Tetris, but you control lateral motion of the falling piece by tilting a 3D printed remote control!)

Team members

Anjali Sreenivas (anjalisr), Aditi Bhaskar (aditijb)

Project description

Layer 1 (P1) - Building Blocks

• Clean falling of colored tetris pieces • Working accelerometer that translates into correct ID of motion (left/right/down) --> ?? interrupt system (based on time) set up? periodic sampling? • Correct handling of left/right/down motion (software/graphics) • Single row clearing functionality – clears all filled rows after move • Scoring system • End game functionality

Layer 2 (P2) - Tying Game Together!

• Ability to rotate falling tetris pieces (in increments of 90 deg clockwise) -- software side • Button configuration (interrupt system) to support user-controlled piece rotation • Support for double/triple row animation clearing • Servo motor/vibration triggered when user clears row • Visible queue of next 3 pieces

Layer 3 (P3) - The Cherries on Top :)

• Gradient squares in tetris pieces! • 3D printed remote control to encapsulate all sensors • Replay screen • Tetris theme song • Leaderboard (name + score) -- keyboard integration

Hardware, budget

Budget - $38 ish

Things we still need (to borrow):

  • 3-5ft HDMI cable -- borrow
  • 3-5ft usbC-usbA cable -- borrrow
  • mango pi (additional) -- $20

Things we already borrowed:

  • 1 accelerometer: LSM6DS33 -- $10
  • 1 active buzzer on breakout -- <$2
  • 1 passive buzzer on breakout -- <$2

PARTS / PHYSICAL MODULES

  • Handheld controller device (think Wii remote but simpler)
  • Music (via. buzzer)
  • Connects to monitor via. long hdmi cable (tethered controller) & long usbC-usbA cable (download code + power)

MangoPi (microcontroller) (processor)

  • NEED FROM 107E LAB - another mango pi? (to solder directly to have a more compact remote)

Accelerometer (tilt) (input)

  • FROM 107E LAB -- LSM6DS33 -- Polulu accelerometer
  • MSA311 datasheet (MY_I2C_ADDR = 0x62) -- if I decide to use Adafruit accelerometer

Buttons (as necessary) (input)

  • 1 button configured w/ interrupt

Servo (for vibration/haptic feedback) (output)

Active/passive buzzer (music!) (output)

Itemize what hardware, if any, you need and your plan for acquiring it. Rough budget for the project. We can reimburse cost of parts up to $20 per person.

Tasks, member responsibilities

Anjali (Graphics / Game Display)

  • Core software underlying game functionality/display
    • Graphics display & update algorithms
    • Falling tetris pieces
    • Handling motion of pieces (right/left/down)
    • Handling rotation of pieces
    • Row clearing

Aditi (Sensors / Actuators / Input-Display Integration)

  • User input & actuators reading/processing + integration with game
    • CAD/engineering of 3D print remote control
    • Accelerometer module & interrupt config
    • Button system
    • Servo/vibration output
    • Piezo buzzer (song)
    • Scoring / additional game feature support

Schedule, midpoint milestones

What are the one-week goals you plan to meet for next week? ANJALI After high-level architecture plan...

  • Set up underlying grid graphics system structure
  • Set up updating / piece motion framework
  • Set up left/right/down movement in conjunction with falling piece - temporarily use keyboard interrupts
  • Random config of falling piece
  • Stretch goal -- start workig on piece rotation

ADITI

  • obtain/solder all materials
  • working accelerometer (driver + fix drifts + interface to get useful data (eg. "tilted left") easily)
  • buttons & potentially other sensors/actuators
  • interrupts handled for all sensors; easy implementation offered
  • test cases for all of the above
  • remote CAD -- improve!
  • read up on scoring system

Resources needed, issues

  • Answered below!!
  • Are there books/code/tools/materials that you need access to?
  • What are the possible risks to overcome? What are you concerned about?
  • How can we help you succeed?

References

  • References linked in materials section

Risks

HARDWARE

  • accelerometer (Aditi wants to write her own driver for the MSA311?? maybe?)
  • mechanical failures SOFTWARE
  • Parallel operating (how do we run the music at the same time as displaying the game? lots of interrupts??)
  • Game optimization / speed when it comes to redrawing -- efficiently handling rotation, lateral motion
  • Multiple interrupts changing the same static variables (cooridnate position of falling piece)

Route for success

  • Aditi - I will definitely be coming by to office hours/posting on the Ed for help
  • Anjali - encouragement along the way, especially when I get stuck or nervous! Patience / willingness to let me walk through my code and potentially offer a debug idea when I run into a bug I can't figure out :'/ THANK YOU in advance!!! <3 We appreciate you all!
