我现在面临的问题是arduino uno编程软件要求我在无效之前插入逗号或分号（sketch_apr04b：16：错误：预期'，'或';'在'void'之前），我不会知道为什么以及何时这样做会告诉我相同的答案。
这是我的代码

您的代码有三个语法错误：
所有分号都用于标记语句的结束。 #include不是声明，因此不应包含分号。
与分号之前一样用于语句的分隔符。然后你应该把它包含在两行中。
#include <Servo.h>; <----------------------- ERROR 1
Servo servo;
void setup () {
servo.attach(9);
servo.write(0);
Serial.begin(9600);
}
int seconds = millis()/1000;
int degs = 0;
int time = 0;
int runs = 0 <----------------------------- ERROR 2
void loop() {
// put your main code here, to run repeatedly:
seconds = millis();
while(time <= 28) {
Serial.write(seconds);
degs = map(time, 0, 29, 0, 179);
servo.write(degs);
delay(1000);
}
runs = runs + 1;
time = seconds * (runs*29) <--------------- ERROR 3
servo.write(0);
time = 0;
}
答案 1 :(得分：0)
＆＃39;时间=秒*（运行* 29）; ＆＃39;。
在arduino C中，每一行必须以; 完成。
答案 2 :(得分：0)
你忘记了分号，“;”在这些行之后
time = seconds * (runs*29)
和
int runs = 0
答案 3 :(得分：0)
#include <Servo.h>;
Servo servo;
void setup () {
servo.attach(9);
servo.write(0);
Serial.begin(9600);
}
int seconds = millis()/1000;
int degs = 0;
int time = 0;
int runs = 0 <---- HERE
void loop() {
// put your main code here, to run repeatedly:
seconds = millis();
while(time <= 28) {
Serial.write(seconds);
degs = map(time, 0, 29, 0, 179);
servo.write(degs);
delay(1000);
}
runs = runs + 1;
time = seconds * (runs*29)<----- HERE
servo.write(0);
time = 0;
}
