Project 1 - A Nonsense Theater

Idea

We made a small interactive theater that includes a rotating palm tree, a bird catch a fish occasionally, and a blinking orange light.

Use a right-angle gear motor with motor driver and rope to make a scrolling structure that moves the bird up and down.
Servo motor powers the palm tree rotate from and back 180 degrees.
Use an IR distance sensor to detect the audience's position: when the audience gets closer to the nonsense theater(approx 30cm), the palm tree will stop rotating.
When the audience is close to the nonsense theater, the microphone component is active to detect whether the audience is speaking. If the audience is speaking or making sounds over a certain volume, the orange light will switch on, and the bird will fly down and back.

Group Working

We used external power and a 7805 regulator to power the servo motor. Then we glued the foam board that supports the palm tree with the motor.

We used a thicker rope to make the scrolling and fish line connect with the bird, so the audience wouldn't see the back scene.
