按下按钮后延迟伺服运动 - Arduino

Question

Recently I have been working on a project where the main goal is to move a servo on a model rocket to deploy a parachute. I want to make is so that 10 seconds after I press the button the parachute is released. I have some code for this already but It is not working, as it stops the code completely. Does anyone know how to fix this?

#include <Servo.h>

// constants won't change
const int BUTTON_PIN = 7; // Arduino pin connected to button'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 = 0;          // the current angle of servo motor
int lastButtonState;    // the previous state of button
int currentButtonState; // the current state of button

void setup() {
  Serial.begin(9600);                // initialize serial
  pinMode(BUTTON_PIN, INPUT_PULLUP); // set arduino pin to input pull-up mode
  servo.attach(SERVO_PIN);           // attaches the servo on pin 9 to the servo object

  servo.write(angle);
  currentButtonState = digitalRead(BUTTON_PIN);
}

void loop() {
  lastButtonState    = currentButtonState;      // save the last state
  currentButtonState = digitalRead(BUTTON_PIN); // read new state

  if(lastButtonState == HIGH && currentButtonState == LOW) {
    Serial.println("The button is pressed");
    time.delay(10000)
    
    // change angle of servo motor
    if(angle == 0)
      angle = 90;
    else
    if(angle == 90)
      angle = 0;

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

In Arduino, a delay is usually done with delay(10000); (for 10 seconds). I've never seen or heard of the time.delay() function, so that might be the issue. Otherwise the code looks like it should work as you want.

It also might depend on the board you're running it on. I remember having issues using delay() for long periods on an ESP8266 although I'm pretty sure that it is fine for tens of seconds.
