Build the Circuit¶

Load the Code and See What Happens¶
Load the code file (1.6_vanishing_vase.sb3
) to Scratch 3.
When you use a magnet near the reed switch module, a vase will appear on the stage, take away the magnet and the vase will disappear.
Tips on Sprite¶
Select Sprite1 and click Costumes in the top left corner; upload desk1.png and desk2.png from the ~/raphael-kit/scratch/picture
path via the Upload Costume button; delete the default 2 costumes, and rename the sprite to desk.

Tips on Codes¶

When the magnet is close to the reed switch module, gpio17 is low, and the costume of the desk sprite is switched to desk1 (the vase is still on the desk).

After taking away the magnet, gpio17 is high, at this time the costume of the desk sprite is switched to desk2 (only one desk).
