HARDWARE & PROGRAMMING
In the spring of my junior year at Princeton, as part of my electrical engineering departmental class Designing Real Systems (colloquially coined "Car Lab") I worked with a partner to design and implement hardware and software for a small electronic car. The first phase of the project was speed control, autonomously maintaining the speed of the car at 3 ft/s (on both flat and inclined terrain) using sensors and basic control theory. The second phase, navigation, involved implementing autonomous line following using a camera and basic control theory. Finally, we spent the remaining six weeks of the semester on an independent project: designing and implementing a system to find a ball and shoot it into a goal using sensors and a deterministic finite state machine.
As part of my Electronic Circuit Design, Analysis, and Implementation class sophomore year at Princeton, I worked with a partner to design, build, and analyze a basic electrocardiogram consisting of an instrumentation amplifier, variable-gain amplifier, band-pass filter, notch filter, and display circuit. We successfully measured the cardiac signals coming from a human heart and outputted a clean electrical signal. We then implemented a Song-filter switching circuit and LED heart array controlled by an Arduino board to visualize the cardiac wave.
