小车循迹代码 C8T6 - Arduino 循迹小车编程示例

循迹代码 C8T6 可以是指使用 C 语言编写的控制小车循迹的代码。以下是一个简单的 Arduino 循迹代码示例：\n\nc\n// 定义引脚连接\n#define LEFT_SENSOR_PIN 2\n#define MIDDLE_SENSOR_PIN 3\n#define RIGHT_SENSOR_PIN 4\n#define LEFT_MOTOR_PIN 5\n#define RIGHT_MOTOR_PIN 6\n\nvoid setup() {\n // 初始化引脚\n pinMode(LEFT_SENSOR_PIN, INPUT);\n pinMode(MIDDLE_SENSOR_PIN, INPUT);\n pinMode(RIGHT_SENSOR_PIN, INPUT);\n pinMode(LEFT_MOTOR_PIN, OUTPUT);\n pinMode(RIGHT_MOTOR_PIN, OUTPUT);\n}\n\nvoid loop() {\n // 读取传感器值\n int leftSensorValue = digitalRead(LEFT_SENSOR_PIN);\n int middleSensorValue = digitalRead(MIDDLE_SENSOR_PIN);\n int rightSensorValue = digitalRead(RIGHT_SENSOR_PIN);\n\n // 判断传感器值，根据循迹情况控制小车运动\n if (leftSensorValue == HIGH && middleSensorValue == LOW && rightSensorValue == LOW) {\n // 左传感器检测到黑线\n // 向右转\n digitalWrite(LEFT_MOTOR_PIN, HIGH);\n digitalWrite(RIGHT_MOTOR_PIN, LOW);\n } else if (leftSensorValue == LOW && middleSensorValue == HIGH && rightSensorValue == LOW) {\n // 中间传感器检测到黑线\n // 直行\n digitalWrite(LEFT_MOTOR_PIN, HIGH);\n digitalWrite(RIGHT_MOTOR_PIN, HIGH);\n } else if (leftSensorValue == LOW && middleSensorValue == LOW && rightSensorValue == HIGH) {\n // 右传感器检测到黑线\n // 向左转\n digitalWrite(LEFT_MOTOR_PIN, LOW);\n digitalWrite(RIGHT_MOTOR_PIN, HIGH);\n } else if (leftSensorValue == HIGH && middleSensorValue == HIGH && rightSensorValue == LOW) {\n // 左中传感器检测到黑线\n // 向右转\n digitalWrite(LEFT_MOTOR_PIN, HIGH);\n digitalWrite(RIGHT_MOTOR_PIN, LOW);\n } else if (leftSensorValue == LOW && middleSensorValue == HIGH && rightSensorValue == HIGH) {\n // 中右传感器检测到黑线\n // 向左转\n digitalWrite(LEFT_MOTOR_PIN, LOW);\n digitalWrite(RIGHT_MOTOR_PIN, HIGH);\n } else if (leftSensorValue == HIGH && middleSensorValue == LOW && rightSensorValue == HIGH) {\n // 左右传感器检测到黑线\n // 停止\n digitalWrite(LEFT_MOTOR_PIN, LOW);\n digitalWrite(RIGHT_MOTOR_PIN, LOW);\n }\n}\n\n\n注意：以上代码仅为示例，具体的引脚连接和逻辑判断可能需要根据实际情况进行调整。
