Building Electrical Circuitry & Coding

During my 1st year of undergraduate studies, I worked with two teammates to build a moving "animal" in a makeshift exhibit that would interact with people as they walked by. As the Mechatronics Design lead, I primarily focused on coding the Arduino program and doing the electrical circuitry for the sensors!

​

• Our design for the animal was for the eyes to illuminate when a user placed their hands through two trees in our exhibit. In practice, I coded the break-beam sensors that would detect when a person placed their hands between the trees that had the two sensors on either side.

• In another interaction aspect, when a user pushed a button in our exhibit, a servo motor would move 90 degrees and trigger the distance sensor, which would in turn cause the dual stepper motors to move the animal up the dual rack and pinion system.
