Week 4 Updates
4/25/18
The build team (Zarraf, Casey, and Vicki) finished the frame of our box! Mia is going to purchase fabric to cover the sides to look like a "puppet show" and cardboard or plywood for the bottom. The build team also made a platform to stand the smaller bears in the background to draw attention away from the bottom of the structure where the larger bear is laying down ready to spring up.
Stuti and Mia continued to work with the motor setup and code. Dr. Terranova suggested a Ardumoto shield to include on the top of the Arduino Uno in order to bypass the need for lots of transistors, diodes, and resistors. After tinkering with the Ardumoto, we were able to use a code found on the internet to make the motors move and reverse directions at different speed.

Stuti and Mia met again today to finalize the code to make the largest bear's arms move up and down. We attached chopsticks to each of the gears on the motors to insert into the bear's arms to animate them. The code found from the link below works well, but we had a hard time getting the bear's arms to move with such a small motor. So, we can either find another motor, test more combinations of speed and delay in the code until we find one that works, or make the connections between the motor gears and the chopsticks stronger.
