Prototype 1

To create my first prototypes I used the Arduino Uno and a couple of sensors. The first circuit I created used a photosensor and an LED. When the photosensor detects darkness the LED turns on.

The second cicrcuit I created used a distance sensor and a piezo buzzer. When the distance sensor detected movement nearby the buzzer played a high pitched tone. When it detected movement further away the buzzer played a lower tone. These circuits that I created forced me to practice with the Arduino in order to understand how electricity works and how to talk to the circuit from my computer.
