  • 2 x black A4 paper
  • Cardboard
  • Scissors
  • Penknives
  • Colored Markers
  • double sided tape
  • scotch tape

    To Print
  • 1 x base template
  • 1 x animation strip template

Step 1

Instructions

(a) Print and cut the base
(b) Then, paste it on a cardboard
(c) Using a penknife, trim the excess cardboard
(d) Poke a hole at the center of the base




Materials

1 x base printout

Step 2

Instructions

(a) Print and cut out the side section. We are going to use this as a template to make 4 black side sections. A penknife is recommended to cut out the slits of the side section.

(b) Trace out the side section template on a piece of black coloured paper. We gonna need four of these.

ps : black is used for the side sections because its gonna emphasize the contrast of the animation strip




Materials

2 x A4 black colored paper
side section printout
penknife
scissors

Step 4

Instructions

Connect the tabs of the 4 side section to make a long strip.
Do not close the two ends yet!




Materials

Step 5

Instructions

Paste the black side section on the black cardboard. Make sure the white base is facing up!

Tip: Tape the sides down section by section!




Materials

Step 6

Instructions

Now, it's coding time!


Step 7

Instructions

(a) We will be using an extension package to make our servo move! Click on the Advance drawer and select extensions.
(b) In the search bar, type in continuous servo
(c) Make sure you select the correct one!




Materials

  • 1 x micro:bit

Step 8

Instructions

(a) Plug a breakout board to micro:bit
(b) Plug in a continuous servo on pin 1




Materials

  • 1 x micro:bit
  • 1 x breakout board
  • 1 x continuous servo

Step 9

Instructions

We will use the continuous servo blocks to code the servo to spin when button A is pressed and to stop when button B is pressed.

(a) Drag in an on Button A pressed block
(b) From the ContinuousServo drawer, drag in a spin one way P1 block
(c) Drag in an on Button B pressed block
(d) From the ContinuousServo drawer, drag in a Turn off motor at P1

Note that in this activity, we will keep the servo's speed to the maximum. You can slow them down if you would like


Step 10

Instructions

Download the code into your micro:bit and we are done with the coding!


Step 11

Instructions

(a) Paste the servo at the base of the zeotrope
(b) Plug-in the battery pack
