if(serial.available())是一个条件语句，用于判断串口缓冲区是否有数据可读。如果有数据可读，该语句返回true，否则返回false。在Arduino编程中，该语句通常用于检查是否接收到了从串口发送过来的数据，以便对数据进行相应的处理。例如，可以使用该语句判断是否接收到了特定的指令，然后执行相应的操作。一、螺纹...

if(Serial.available()>0)这个必须要大于0 主要看Serial.available()这个函数返回值的类型和值
TIP: Factor code for the compiler to process chains of Arduino if else code.For example the trivial code above could be re-written as: static int command=0; void d_action(void) { Serial.println("data"); command = 1; } void b_action(void) { Serial.println("begin"); command = 2;...

In order to connect the nerf gun to the Arduino and later on to the base of the turret we will need to make a few adjustments. First, we need to open up the gun. You can do this by pulling of the orange handle on the side and then removing the handgrip and screws from the body...
