11/26/2025 3:39 PM - creating the design of the enclosure in fusion 360

So for the first step, I was wondering what I could make. So I thought I’d make a game with Arduino. I decided to create a Cyclone game those large arcade games but I’ll make it small, using a simple Arduino Mega microcontroller and some LEDs arranged in a circle, with a light in the middle so we can see if we have stopped the light-chasing LEDs correctly. First, I hopped onto Fusion Pro to decide exactly what I was trying to make. Below are the designs I created. This took me around two and a half to three hours to make, and it is a rough idea of what I’m trying to create with my Arduino Cyclone game.

11/26/2025 3:54 PM - Designing the schematics and making and routing the PCB.

After designing the case, I started on the PCB. I used EasyEDA because. First, I worked on the schematics. I included an Arduino Mega 15 LEDs—one red and an RGB LED All the LEDs are standard 5 mm types. I spent about one hour designing the schematics. Then I spent another hour to an hour and a half routing and creating the PCB. Overall, this step took me about three hours. After that, I checked all the connections and tested if the schematics would work in simulation software which took me around 1 and a half hour

11/26/2025 4:11 PM - making the top plate

In this step, I decided to make a top plate from a plywood board for the Cyclone game where I would place the LEDs. I took a piece of plywood and drew a circle on it. I did some basic math to mark the points at equal distances, ensuring the LEDs would be evenly spaced. This took me about an hour because I'm not great at math. Then I started drilling the holes. I used a makeshift tool I fashioned from a screwdriver to drill the holes with hand. I also used a sharp tool similar to a screwdriver to chip away at the edges of the circle. Once the circle was roughly separated, I sanded it down. This task was quite heavy, and it took a long time. I spent four and a half hours just cutting the circle and poking each hole by hand. After that, I began placing each LED and applied super glue to keep them in place. Finally, I connected the ground pins of all the LEDs together to create a common wire for the Arduino.

11/26/2025 4:23 PM - making the circuit

In this step, I started the connection process and decided to make the circuit using an Arduino Mega. Since there were so many LEDs, this was a difficult task. I used jumper wires because I didn’t want to solder directly to my Arduino Mega. I had to connect a jumper wire to each of the LEDs in the plywood, including the RGB LED. I cut each jumper wire in half, connected one end to the LED, and the other end to the Arduino Mega, following the circuit I had created. I soldered everything, and this took me around 2 hours to do this all. After completing all the connections, I moved on to the step of creating the outer body.
I forgot to click pictures of this step, and I will add a picture of the inside once the project is complete

11/26/2025 4:26 PM - creating the power supply

For this project, I built a custom power supply. I had a broken power bank and used a battery from an old device. I took apart the power bank and removed its module. Then, I used the battery and soldered the board together to create a custom power bank. After that, I charged the module to full. This process took me about 30 minutes to finish.

11/26/2025 4:39 PM - Creating the body and adding the switch

So finally, I had to create the switch that stops the LED, which is the heart of the whole project. I also had to create a body for the project. To make the body, I first used cardboard, but after that, the project looked too ugly. So I decided to make it look better by adding craft paper on top. I also made a custom switch case out of ice cream sticks and a case for it using a marker that I reshaped. This was a crazy step. I had to do all the craft work, and I’m not very good at craft — as you can see by looking at the project itself, I’m not very good at designing stuff. This whole step took me around four hours, and making and soldering the button also took me about an hour. So at this stage, I finally created the project case and the switch.

11/26/2025 4:48 PM - coded the arduino

In this step, I wrote the code for the project in C using the Arduino Mega. The code makes the LEDs chase around the circle one by one, creating a light-chasing effect. I also programmed it so that when the button is pressed, the game stops and the active LED stays on. Depending on which LED stops, either red or white, the RGB LED changes color to show the result. The code controls all the LEDs, handles the button input, and manages the game flow. It ensures the chase runs smoothly and the result is displayed correctly. It’s simple, but it makes the game work just like the Cyclone arcade game.
