A. Ideation & Preparation

The sketch for the system

After analyzing the level of difficulties and the aesthetics of many of our ideas, we decided to move further with the magic ball theme, which is an interactive installation allowing the users to trigger the physical and visual effect when they get closer to the installation. The input will be the users' distance with the sensor, and the output will be in three parts: the LED's lighting, the fan's wind, and the speaker's music.

• Interaction process

Original status: LED lights keep breathing/ feathers on the button

When the user gets closer: the ****sensor detects the distance — LEDs keep lighting — the speaker plays the Harry Potter theme song — two fans start running - feathers float up

• Material List

We made a material list for the whole project and mainly ordered the materials online. Besides that, we surprisingly found something useful from the rack on the floor.

• [x] Acrylic display cube
• [x] Fan
• [x] Power
• [x] Light Globe
• [x] LED
• [x] Feathers
• [x] Speaker
• [x] Sensor
• [x] Box/light globe holder

B. Physical Computing

We want to connect the sensor with three different output sources, so we first spent a lot of time figuring out how the fans would work with the sensor.

• Testing the fan

  

  We first tried to control the fans with the potentiometer. We have tried many fan models in order to get the strongest wind to blowing up the feather. To be clearer, we also used Arduino Uno in this project.
