It took more than two months from inspiration to the exhibition. Because of the impact of the epidemic, we were forced to make many changes to our project. For example, from the original samurai to a gunman and the weapon from a katana to a laser gun. But for us, we have largely completed the plan in the proposal, and we didn't build a castle in the sky.

This video can show how to use this device for those friends who have not participated in our exhibition. And to facilitate the visually impaired people to use what optimization we have done. And how this device works,

In fact, I have experience using Arduino last semester, but the rejection was severe at that time because I wouldn't say I liked programming. However, in this project, I was responsible for a lot of code-related work. I had to learn about programming. Through this project, I know how to use the Bluetooth module and wifi module to form a small Internet of Things. I even now know how smart homes work. In the process of our project, we also made an intelligent watering device, which looks interesting.
