Students presented their project.
Matt built a circuit with nonlinear effects. By varying the driving amplitude, chaotic behavior can be observed on the oscilloscope.
Kristine constructed an exclusive OR gate, which is a logic gate that enables the output LED to turn on when only one of the input sources is “high.”
Katelynn and Kayla used Arduino, phototransistors, and a tri-color LED to create a lamp whose color corresponds to the RGB components of the light coming into the circuit from the environment.
