The display is made up of 18 LEDs organized into 9 segments where there is a blue and red LED in each segment. There is a single button that the player uses to control where they will place their mark. There is also a micro-USB port that is used to power the card.
An ATmega328P-AU in a TQFP package is used as the brains to control everything. It is bootloaded with the Arduino Uno bootloader since I found that to be the most convenient and low-cost way to program it (although there are other ways to do it).
Here is a video of the card. Currently, one segment doesn't work in the video because I accidentally connected 2 pins to input only pins. However, I will make a follow-up part 2 video with the fixed design. The schematic and code on this project page do have the fixes in case you'd like to make your own.
I am also facing problems in running with default code and I have tried to search for it online but can't found about it anywhere. Recently, I was searching for the https://www.ogscapital.com/article/soap-making-business-plan-sample/ online and while searching for it, I have found your post in which I have found my problem solution. Thanks for the help.
