Approach
I decided to use the egg shell to mix the 3 LED colors and create a "party" like ambient for this project. I also used the motor to create a very simple "optical illusion" on top of the shell. (I could have drawn better if I were a better artist..) All the codes were modified based on previous and current assignment. I have set the potentiometers' settings to change the speed of blinking and also the speed of the motor.
