1. 從序列埠控制LED燈，電路須具備五顆LED輸出，一顆開關輸入，功能如下
(1) 一開示顯示視窗會顯示
Press 0 to start the system
(2) 從序列埠發送0時，監控視窗顯示
Welcome to LED display system, send the instruction to the Arduino, led will show the different operation mode. (1) Mode1
(2) Mode2
(3) Mode3
(3) 若是輸入的指令不為1,2,3，則視窗會顯示，
Wrong instruction, try again, please!
Welcome to LED display system, send the instruction to the Arduino then LED will show the different operation mode. (1) Mode1
(2) Mode2
(3) Mode3
(4) 模式一，自訂led閃爍的模式(不可重複)
(5) 模式二，自訂led閃爍的模式(不可重複)
(6) 模式三，自訂led閃爍的模式(不可重複)
(7) 當Arduino收到開關序號時，顯示視窗會出現
Turn off the leds.
(8) 承上，電路停止閃爍，並顯示(並從新開始等待命令)
