Project page: Smart Blinds

Week 1

September 11
0.5hr Sam

  • Created a wiki page.

September 12
1hr
Sam and Toby

  • Met with TA Will
  • Learned the basis of wiki.
  • Studied the circuit and built the night light on the breadboard.
  • Discussed the material needed for the project.

September 14
2hr Toby

  • Created a proposal draft

2hr Sam and Toby

  • Met with TA Will
  • Finish soldering Night Light on perfboard
  • Discussed proposal
  • TA gave advise on the proposal

Week 2

September 18
2hr Sam

  • Created budget
  • Created Gantt Chart

September 19
0.5hr Toby

  • Finished the proposal before meeting with the instructor

2hr Sam

  • Finalized Gantt Chart and material list

0.5hr Toby and san

  • Meet with TA and instructor

September 21
2hr Toby

  • Finalized proposal based on instructor's advice
  • Created a presentation power point


Week 3

September 24
3hr Sam

  • Started to learn Onshape
  • Designed rough draft of night light case

September 26
1hr Sam

  • Updated Gantt Chart

1.5 hr Toby

  • Looked for user interface and AC/DC convertor online
  • Updated budget and presentation

September 28
2hr Sam

  • Learned additional Onshape techniques
  • Finished Night Light Case

Week 4

September 30
2hr Toby

  • Ordered material online
  • Reviewed programming for Arduino
  • Learned the code of Arduino to stepper motor

October 2
1.5hr Sam

  • Researched onshape design techniques for fitting parts
  • Exported Night Light case stl file

October 3
1hr Sam and Toby

  • Met with TA Will
  • Discussed the Arduino programming of photo-resistor and stepper motor control

October 5
2hr Sam and Toby

  • Built the circuit for stepper motor and photo-resistor
  • Wrote codes for Stepper motor and photo-resistor separately
  • Succeeded in turning on the stepper motor and reading inputs from the photo-resistor

Challenges:

  • The purchased photo-resistor did not provided desired inputs, so our team built a simple circuit containing a photo-resistor
  • Need to find the correct delta timing for photo resistor reading in Arduino coding
  • Need to figure out the codes for stepper motor in order to achieve desired effects

Week 5

October 7
1.5hr Toby

  • Wrote codes to gain the correct outputs of photo-resistor
    • The arduino will read 100000 inputs over a time interval of about 3 minutes and calculate the average of the total inputs

2hr Sam

  • Took measurements of blind components and stepper motor
  • Created a preliminary design of motor to blind connection

October 8
3hr Toby

  • Met TA Will
  • Found a more useful arduino library for the driver online
  • Figured out the functions of the codes
    • Able to turn on the stepper motor for a desired number of rotations
    • Able to stop and reverse the stepper after a certain number of rotations
  • Built a primitive interface between the stepper motor and the luminosity reader

Challenges:

  • Have yet tested the codes
  • Some loop logic errors may still exist

October 9
2.5hr Sam

  • Started 3d design of part to translate stepper motor rotation to blind movement
  • Updated Gantt Chart


October 10
2hr Sam

  • Finished 3d design of adapter
