Preset Demo Tutorial
Press the "Reset" button，reset the system.
Use the Joystick to control the movement (e.g. move around, up and
down) when playing the snake game.
Software Installation
1.Download the Arduino IDE
2.GitHub:
• When configure the Arduino IDE Hardware Platform and the COM Port (the
COM Port is allocated randomly by your computer), please use IDE for code
writing or use Github routine code to develop.
