The Emotion Compass-- Wunderkind

Arduino Development

Introduction

People are not used to show their feelings, but feelings run through life every moment.

Wunderkind is a little compass which will not only help you to point the north direction but also point the right way to the person or places (individual model) match with your emotion.

Basic instruction

Users hold the little device and turn it on; then rotate the compass. As soon as the compass was turned, the LED lights around the compass will light up following the rotation. Each light according to one emotion. When user stop, the corresponding emotion is chosen. Then the compass will match a person or destination found and show the direction with the arrow on the surface. Following the arrow, user will reach the destination/person; there will be an excited blinking shown on the LED ring, then it goes off.

Components required Software

1. Arduino Uno×1, arduino ide,
2. Breadboard×1, Inkscape 0.91(or any drawing tool exports files in ".svg" format).
3. Laser cutter×1,
4. Wood board×1,
5. neon pixel(×24) ring×1,
6. servo motor×1,

Step1: Build components of the compass with laser cutter

Preparation: laser cutter, wood board, Inkscape 0.91(or any drawing tool which can export files in ".svg" format).

Print out the elements of compass and the base with laser cutter. (download the design drawing attached to this tutorial)

Step 2：Assemble Arduino Fittings

Assemble every elements according to the circuit diagram.

Step3: Control the neon pixel ring

1. Opening animation
2. Idle state
3. 4 quarters of different color
4. light up follow the rotation
5. display neon turning wheel
6. brightness control
7. show in single color
