  4. Our final prototype 4

  5. Overview - Project Outline - Research & Literature Review - Experiments - Prototyping Process 5

  6. Project Outline 6

  7. Main Objective Create a waterfall display with oil as the medium 7

  8. Secondary Objectives Using the prototype as a proof-of-concept: a. Improve the maximum display quality of the prototype b. Make the prototype more aesthetically pleasing 8

  9. Interest Technology & This Art Programming Project 9

  10. Research & Literature Review 10

  11. Arduino Microcontrollers ◆ Different versions for different needs (Credit to: Arduino, at arduino.cc) 11

  12. Arduino Leonardo USB communication Ground pins Digital pins for communication Credit to: Sparkfun 12

  13. Subtractive Colour Theory K Credit to: Wikipedia 13

  14. Experiments 14

  15. Water, Oil & Food Colouring Water, oil and food colouring do not mix together Water droplets with food colouring Food colouring droplets 15

  16. Water, Oil & Food Colouring - Dropped food colouring through oil - No stained oil - Dropped water with food colouring through oil - No stained oil - Drops merged over time - Conclusion: Food colouring is not oil soluble 16

  17. Speed of Water through Baby Oil - Dropped coloured water through baby oil - Varying heights - Speed of water through baby oil is roughly 3.1 cm/s 17

  18. Speed of Water through Baby Oil Speed = Reciprocal of Gradient = 3.1 cm/s 18

  19. Prototyping Process 19

  20. The previous prototype... 20

  21. Problems of old prototype 1. Aesthetically displeasing 2. Water leaked often from the jar 3. Low display quality 21

  22. Improving... 22

  23. Improving... Water leaked often from the jar - Better sealage - Replaced containers 23

  24. Improving... Low display quality - Oil instead of air - Slows water down 24

  25. Slave Master Serial Communication Valves 25

  26. One-Way Serial Communication Master: Open Valve at Port 08 Credit to: Sparkfun 26

  27. Programming ◆ Instructions - cycle through each valve from the first to the last at a set interval (proof-of- concept) ◆ Patterns can be added through the code for a performance 27

  28. Circuitry 28

  29. Areas for Further Research ◆ Using a backlit board ◆ Additive Colour Theory ◆ Higher control over aesthetic design ◆ Change colours 29

  30. Our final prototype! 30
