Electrocardiogram (EKG)

Image 3
Designed and constructed a circuit (Image 1) to create a bandpass filter in order to isolate heartbeats. Image 3 shows how my EKG cleanly filtered a heartbeat from the noisy simulation in Image 2.
Responding To Music
LED Array Boombox
Turn On/Off One By One
Soldered an LED array and programmed using an Arduino. In the first video, I turned the LED array into a boombox that both plays and responds to music by turning on certain LEDs based on the frequency of the song. In the second video, I made a program that turns on the LEDs one after another. Finally, in the third video, users are able to input the exact LED they either want to turn on or off.
Traversing Through LEDs
Programmed Extra States
Useless Box
Used a limit switch to create a “Useless Box” that turns itself off when turned on. In the first video, I used an Arduino to program extra states into my box. In the second video, I solely used circuit design to control my box.
Fully Mechanical
Solar Powered Flashlight
Used a solar panel and switch to design a flash light.
