LED located on each floor that lights up blue when the elevator is called to that floor and turns off when the elevator arrives. Single multicolored LED located at the top of the elevator that turns red to indicate that the elevator is moving downwards and turns green to indicate that it is moving upwards.
Dowel connected to a motor. One string attached the dowel and the elevator, and another string attached to the dowel and a weight to act as a counterweight.

Robot Arm Battle
Design Challenge:
Build a robot arm with a 9 volt electromagnetic tip that will pick up magnetized balls and place them in an adjacent rack. The robot arm will compete to pick up more balls than another team.
​
Specifications:
-
The robot’s motion must be controlled by three syringes
-
An 8’’ x 8’’ x ¾’’ piece of wood is used as the base
-
An electromagnet is used to pick up the balls
Hydraulic robot arm with electromagnet to pick up magnetic balls
Hydraulic robot arm with electromagnet to pick up magnetic balls
Dice switched off or not connected to the battery.
Soldered the components onto the circuit board and trimmed the excess wire
The dice generate random numbers each time the button is pressed (press and hold to keep the numbers)
Dice switched off or not connected to the battery.
Electric Dice
Design Challenge:
Place the components and solder them onto the circuit board to create an electronic dice.
Function:
When the button is pressed, two randomly generated numbers are lit up using LEDs.
Collage Using Java
Design Challenge:
Create a collage of three filtered versions of one picture side by side using Java.
​
Function:
This collage creates a collage of a negative version of a photo, a purple tinted version of a photo, and a mirrored version of a photo. The filters and collage code were all written in Java.
