Bill of Materials

• Liquid timer: Key component of this project. Displaying rotation information.

• Wood stick: Another key component of this project. Act a a triger for users to input rotation movement.

• Hall effect sensor and magnet: They are paired for us detecting the rotation movement from wood stick.

• Servo motor: Transfering  rotation movement form contorllor to liquid timer.

• Neopixel LED: 

• Fabrication: Wood, acrylic, Laser cut, 3D printing.
