Over the semester, I built a simple Arduino-based Morse code prototype. It started with just three buttons to create Morse code messages, which were then turned into sound. I quickly realized that keeping it on one device didn’t make much sense, so I connected the Arduino to Wi-Fi and used OSC to send messages to my laptop. From there, I added a decoding function that translated Morse into readable text. In the final step, I built a basic web interface where you could type a message, send it to the Arduino, and see it displayed on an LED matrix. My idea is to use this setup to teach kids about encryption in a playful way. Along the way, I learned a lot about Arduino syntax, using libraries, and how to build Wi-Fi and web-based interfaces—opening up tons of new creative possibilities for me.
