Below I will post some of the frequent mistakes you have made in the seminar.
//MISTAKE ONE ***Notice the capital letter ***注意区分大小写字母 pinMode（LED，OUTPUT） //正确 pinMode（LED，output） //错误 pinmode（LED，OUTPUT） //错误
//MISTAKE TWO ***Forget about the {} for loop ***在for循环后要加入一对中括号限定其作用范围 void loop() { for (int i=0; i<5; i++) { digitalWrite(Sensor, HIGH); } //此中括号为for循环所修饰 } //此中括号为loop循环所修饰
