Brainstorming

When we first met, we had all studied about circuits individually and came up with three ideas. This week's homework focused on how to create an input switch with a story that makes the LED light up as an output. Our ideas were diverse.

<aside> 💡 Ideas

• Changing the color of the light when a person crosses the signal
• Illuminating the school when a flag is hoisted
• Lighting up the Empire State Building
• Creating a sparkling mood lamp
• Making a proposal lamp that lights up when a ring is worn
• Showing the journey from Korea to New York for studies
• Lighting up the screen when a pen touches it </aside>

We choose…

All of us in our team were Korean and had recently come to the United States to study, so we shared the common experience of moving from Korea to the unfamiliar United States. Therefore, we chose an idea that would represent this transition using LED lights.

Components

To realize this idea, we used LED lights, wires, resistors, a multimeter, a wire stripper, a breadboard, a 9V battery connector, a 9V battery, an Uno Arduino, aluminum foil, insulation tape, soldering, a human figurine, and illustrations of the departure and arrival from Korea and the United States.

Logic of circuit

& Attempts

Since we needed two switches to represent New York and Korea, we had to set up a circuit where the middle wire would activate both the left and right LEDs. Below are the circuit setup and lessons learned from the experiment.
