Your project is amazing.I also got tft shield v.2 for arduino nano and implemented it, and it works very well.However, while using the app for Android that you attached, I wanted to change the behavior in my own way.That is, when the direction button is pressed, the corresponding character such as "F" or "L" is sent only once. But, the way I want to change is while the button is being pressed, the corresponding character is continuously transmitted and send an "S" after the button is released.So, if you don't mind, please send me the source code file of the app for Android by mail. (Your source code is a file written in Android Studio, right?)My email address is zzigrri@gmail.com.Thank you so much.
