好的,这是一个基于Arduino的小车寻迹代码:
```c++
// 定义引脚
const int leftPin = 2;
const int rightPin = 3;
const int leftSensor = A0;
const int rightSensor = A1;
// 定义速度
const int turnSpeed = 150;
const int forwardSpeed = 200;
void setup() {
pinMode(leftPin, OUTPUT);
pinMode(rightPin, OUTPUT);
pinMode(leftSensor, INPUT);
pinMode(rightSensor, INPUT);
Serial.begin(9600);
}
void loop() {
int leftValue = analogRead(leftSensor);
int rightValue = analogRead(rightSensor);
Serial.print("Left Sensor: ");
Serial.print(leftValue);
Serial.print(" Right Sensor: ");
Serial.println(rightValue);
if (leftValue < 500 && rightValue < 500) {
// 直线行驶
digitalWrite(leftPin, HIGH);
digitalWrite(rightPin, HIGH);
analogWrite(leftPin, forwardSpeed);
analogWrite(rightPin, forwardSpeed);
} else if (leftValue >= 500 && rightValue < 500) {
// 左侧黑线
digitalWrite(leftPin, LOW);
digitalWrite(rightPin, HIGH);
analogWrite(leftPin, turnSpeed);
analogWrite(rightPin, forwardSpeed);
} else if (rightValue >= 500 && leftValue < 500) {
// 右侧黑线
digitalWrite(rightPin, LOW);
digitalWrite(leftPin, HIGH);
analogWrite(rightPin, turnSpeed);
analogWrite(leftPin, forwardSpeed);
} else {
// 两侧都有黑线
digitalWrite(leftPin, LOW);
digitalWrite(rightPin, HIGH);
analogWrite(leftPin, turnSpeed);
analogWrite(rightPin, forwardSpeed);
}
}
```
这个代码基本上就是一个无限循环,每次循环都会读取左右两侧的传感器的值,并根据传感器的值来控制小车的运动方向。如果两侧都检测到黑线,小车会向右转,如果只检测到左侧的黑线,小车会向左转,如果都没有检测到黑线,小车会直行。
