GameTube is a project launched by Daddy's Lab for young children. This slide shows the steps to program Scratch with GameTube. I hope you can easily understand how GameTube works.

1. “Making a game to play on a swing”
motivated from 춘향전
※ Contributed as a GameTube™ application

2. MAKE It Yourself!
– Everything’s ready for you.
Imagine wholeheartedly!
– Creativity Matters
– Learn, Design, Make, Share iteratively

3. Linked Data, Linked Economy and
Linked Thinking.
– All subjects are connected in real world.
Knowledge for descendants
– Creating contents for everyone

4. HW: Breadino™ and a few modules
SW: Scratch for Arduino (S4A) as IDE

5. http://www.ohmynews.com/nws_web/view/at_pg.aspx?CNTN_CD=A0001409717

6. Joystick module offers an analog
value 0~1023 for each X-Y axis
– Left & Right : at port Analog4
– Up & Down : at port Analog3
Set the 5 intervals of each direction
–
0…1023
100
− 5 × −1 → {0…5}

7. Scratch uses 480*360 pixels screen
– Origin located at the center

8. Trigonometric functions
– X = cos 𝜃
– Y = sin 𝜃
– 𝜃 is the degree of angle.
Scratch supports mathematics

9. Mechanical energy conservation law
– Swinging pendulum conserves the energy
– Simplifying equation was required for better
performance.

10. Introducing the values for speeding
– Velocity: v =
𝑠
𝑡
(t = time, s = distance)
– Acceleration: 𝑎 =
𝑣
𝑡
=
𝑠
𝑡2
Direction of speed
– Pendulum changes the direction on top
Reducing the speed for each swings
– To emulate the real world

11. Simplicity is hard
rather then easy
– Keep
It
Simple and
Short

12. Version 0.2
– Playing on a swing with joystick

13. Better spites & game scenario
