MAKE It Yourself! – Everything’s ready for you.

Imagine wholeheartedly! – Creativity Matters

– Learn, Design, Make, Share iteratively

Linked Data, Linked Economy and Linked Thinking.

– All subjects are connected in real world.

Knowledge for descendants

– Creating contents for everyone

HW: Breadino™ and a few modules

SW: Scratch for Arduino (S4A) as IDE

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}

Scratch uses 480*360 pixels screen

– Origin located at the center

Trigonometric functions

– X = cos 𝜃

– Y = sin 𝜃

– 𝜃 is the degree of angle.

Scratch supports mathematics

Mechanical energy conservation law

– Swinging pendulum conserves the energy

– Simplifying equation was required for better performance.

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

Simplicity is hard rather then easy

– Keep It Simple and Short

Version 0.2

– Playing on a swing with joystick

Better spites & game scenario
