Arduino Simon Says Game

July 29, 2025 | 3 Minute Read

Hello and welcome! Over the past two weeks, I began working with the Arduino kit, completed several projects from the book, and even created my own project that contributes to the Boston flight stipend!

It didn’t take long for me to get absorbed in the world of electronics. I started watching videos on voltage, current, resistors, LEDs, and more. I quickly got familiar with the kit, installed the Arduino IDE, and added Hackatime to track my hours. Before I knew it, I was already working on the first project from the guidebook.

The first project involved simply connecting one and then two LEDs, so I quickly moved on to the second one, which was wiring three LEDs to a pushbutton. This project gave me a basic but valuable understanding of how C++ and Arduino code work. I completed it soon after and was happy with the result.


The third project used a temperature sensor to measure the temperature of one of your fingers. The last project I worked on was the fourth, as the projects became more time consuming and I needed to focus on logging hours toward the flight cost. But I made sure to read through the remaining projects so I can better understand them moving forward. The fourth project involved three phototransistors, each designed to detect a color: red, green, or blue. These were connected to an RGB LED, which mixed the colors and displayed the result using some simple code.


Once I had finished working with the guidebook, I decided to start one of the projects I had in mind: an Arduino Simon Says game. I began building it in Tinkercad but wrote the code in the Arduino IDE so it would count toward Shipwrecked. It took me about three days to complete the breadboarding and get the code working within the Tinkercad simulations. Once I was happy with the design and functionality, I built the physical version, which was up and running within a day. I made some small changes to the code at that stage, but nothing too big.


Once I was happy with the result, I began working on a demo video, since hardware projects especially require one to be accepted. I took plenty of video clips and screencasts, recorded audio, and even found a song in the YouTube Music Library. In a day or two, I had put together a demo video that I am quite happy with.

Next, I put together the README, added the finishing touches to the repo, and submitted the project for review. If it gets accepted, it would contribute to a grand total of 214 dollars, which is not bad.


Next week, I plan to build a small project similar to this one, and then I’ll be off to Shipwrecked. Also, feel free to check the GitHub repo out and read the README for more information on the project!
