Check the settings for your controller and the port in the Arduino IDE, and try again. For those of you with Mini controllers, skip ahead to the section How to Connect Things to Your Board if you want to see something blink, and then return to this section. Why is this? Well, you ...
int checkSensor(){ //这儿定义了一个整数形函数checkSensor if (analogRead(0) > 400) { //如果读取0针脚的数据大于400的话 return 1;} //返回1,相当于调用这个函数后得到的值是1 else{ return 0; //返回0,相当于调用这个函数后得到的值是0 } } return关键字可以很方便的测试一段代码,而无需“comme...
