arduino - 如何让 2 个引脚做同样的事情？

问题描述

我想让 2 个触摸传感器做同样的事情，那就是移动伺服，但我不知道谁能帮忙？第二个触摸传感器应该命名为 TOUCH_SENSOR_PIN2 我试过但只有 1 可以工作。有谁知道如何使此代码与 2 个触摸传感器一起使用？

这是代码：

#include <Servo.h>

    const int TOUCH_SENSOR_PIN   = 6;   // Arduino pin connected to touch sensor's pin
    const int SERVO_PIN          = 9;   // Arduino pin connected to servo motor's pin
    
    Servo servo; // create servo object to control a servo
    
    // variables will change:
    int angle = 141;           // the current angle of servo motor
    int lastTouchState;      // the previous state of touch sensor
    int currentTouchState;   // the current state of touch sensor
    
    
    void setup() {
      Serial.begin(9600);      // initialize serial
      pinMode(TOUCH_SENSOR_PIN, INPUT);
      servo.attach(SERVO_PIN);       // attaches the servo on pin 9 to the servo object
    
      servo.write(angle);
      currentTouchState = digitalRead(TOUCH_SENSOR_PIN);
    }
    
    void loop() {
      lastTouchState    = currentTouchState;  // save the last state
      currentTouchState = digitalRead(TOUCH_SENSOR_PIN);  //read new state 
    
      if(lastTouchState == LOW && currentTouchState == HIGH) {
    
        // change angle of servo motor
        if(angle == 141)
          angle = 156;
        else
        if(angle == 156)
          angle = 141;
    
    
        // control servo motor arccoding to the angle
        servo.write(angle);
        
    
          }
      }

解决方案

我还没有尝试过，但这应该可以。请替换<pin number>为您的第二个触摸传感器所连接的引脚编号。

#include <Servo.h>

const int TOUCH_SENSOR_PIN   = 6;   // Arduino pin connected to touch sensor's pin
const int TOUCH_SENSOR_PIN2   = <pin number>;
const int SERVO_PIN          = 9;   // Arduino pin connected to servo motor's pin

Servo servo; // create servo object to control a servo

// variables will change:
int angle = 141;           // the current angle of servo motor
int lastTouchState;      // the previous state of touch sensor
int currentTouchState;   // the current state of touch sensor
int lastTouchState2;      // the previous state of touch sensor 2
int currentTouchState2;   // the current state of touch sensor 2


void setup() {
  Serial.begin(9600);      // initialize serial
  pinMode(TOUCH_SENSOR_PIN, INPUT);
  pinMode(TOUCH_SENSOR_PIN2, INPUT);
  servo.attach(SERVO_PIN);       // attaches the servo on pin 9 to the servo object

  servo.write(angle);
  currentTouchState = digitalRead(TOUCH_SENSOR_PIN);
  currentTouchState2 = digitalRead(TOUCH_SENSOR_PIN2);
}

void loop() {
  lastTouchState    = currentTouchState;  // save the last state
  currentTouchState = digitalRead(TOUCH_SENSOR_PIN);  //read new state 
  
  lastTouchState2    = currentTouchState2;  // save the last state
  currentTouchState2 = digitalRead(TOUCH_SENSOR_PIN2);  //read new state 

  if((lastTouchState == LOW && currentTouchState == HIGH) || (lastTouchState2 == LOW && currentTouchState2 == HIGH)) {

    // change angle of servo motor
    if(angle == 141)
      angle = 156;
    else
    if(angle == 156)
      angle = 141;


    // control servo motor arccoding to the angle
    servo.write(angle);
    

      }
  }
