connection of rain sensor and its moduleHere is a wiring diagram for an automatic baby cry cradle using an Arduino, servo motor, rain sensor, sound detector, buzzer, and speaker:
The rain sensor is connected to the Arduino's analog input pin A0, while the sound detector is connected to A1. The buzzer is connected to digital pin 3, and the servo motor to digital pin 9. The speaker is connected to a digital pin 11.
The rain sensor will detect if it starts raining and send a signal to the Arduino. The sound detector will listen for the sound of a baby crying and send a signal to the Arduino if it detects crying. The Arduino will then activate the servo motor to start swinging the cradle gently back and forth and play a lullaby through the speaker. The buzzer will sound if there is an error in the system, such as a malfunctioning sensor.
Note: This is just a basic wiring diagram to give an idea of how to connect the components. The actual implementation may require additional components and modifications to ensure proper functionality and safety.

Here is a sample code that you can use as a starting point for your automatic baby cry cradle project using an Arduino, servo motor, rain sensor, sound detector, buzzer, and speaker:code for this materials
#include <Servo.h>
// Pin connections
const int rainSensorPin = A0;
const int soundDetectorPin = A1;
const int buzzerPin = 3;
const int servoMotorPin = 9;
const int speakerPin = 11;
// Variables
int rainSensorValue;
int soundDetectorValue;
Servo servoMotor;
void setup() {
// Initialize pin modes
pinMode(rainSensorPin, INPUT);
pinMode(soundDetectorPin, INPUT);
pinMode(buzzerPin, OUTPUT);
pinMode(speakerPin, OUTPUT);
servoMotor.attach(servoMotorPin);
}
void loop() {
// Read sensor values
rainSensorValue = analogRead(rainSensorPin);
soundDetectorValue = analogRead(soundDetectorPin);
// Check if it's raining
if (rainSensorValue > 500) {
// Stop swinging and turn off sound
servoMotor.write(90);
noTone(speakerPin);
// Turn on buzzer to indicate error
digitalWrite(buzzerPin, HIGH);
delay(500);
digitalWrite(buzzerPin, LOW);
}
else {
// Check if baby is crying
if (soundDetectorValue > 500) {
// Start swinging and play lullaby
servoMotor.write(0);
tone(speakerPin, 440);
}
else {
// Stop swinging and turn off sound
servoMotor.write(90);
noTone(speakerPin);
}
}
}
libraries needed for this codeHere is a sample code that you can use as a starting point for your automatic baby cry cradle project using an Arduino, servo motor, rain sensor, sound detector, buzzer, and speaker:
Code:#include <Servo.h> // Pin connections const int rainSensorPin = A0; const int soundDetectorPin = A1; const int buzzerPin = 3; const int servoMotorPin = 9; const int speakerPin = 11; // Variables int rainSensorValue; int soundDetectorValue; Servo servoMotor; void setup() { // Initialize pin modes pinMode(rainSensorPin, INPUT); pinMode(soundDetectorPin, INPUT); pinMode(buzzerPin, OUTPUT); pinMode(speakerPin, OUTPUT); servoMotor.attach(servoMotorPin); } void loop() { // Read sensor values rainSensorValue = analogRead(rainSensorPin); soundDetectorValue = analogRead(soundDetectorPin); // Check if it's raining if (rainSensorValue > 500) { // Stop swinging and turn off sound servoMotor.write(90); noTone(speakerPin); // Turn on buzzer to indicate error digitalWrite(buzzerPin, HIGH); delay(500); digitalWrite(buzzerPin, LOW); } else { // Check if baby is crying if (soundDetectorValue > 500) { // Start swinging and play lullaby servoMotor.write(0); tone(speakerPin, 440); } else { // Stop swinging and turn off sound servoMotor.write(90); noTone(speakerPin); } } }
This code reads the analog inputs from the rain sensor and sound detector, and uses them to control the servo motor and play sounds through the speaker and buzzer. The servo motor swings the cradle if the sound detector detects crying, and stops if the rain sensor detects rain or if the baby stops crying. If there is an error, such as a malfunctioning sensor, the buzzer will sound.
Note that this is just a basic example and you may need to adjust the code and add more functionality to suit your specific needs.
For this code, you only need to include the Servo library. This library is used to control the servo motor. To include the Servo library in your Arduino sketch, go to Sketch > Include Library > Servo.libraries needed for this code
cant stop the buzzerHere is a sample code that you can use as a starting point for your automatic baby cry cradle project using an Arduino, servo motor, rain sensor, sound detector, buzzer, and speaker:
Code:#include <Servo.h> // Pin connections const int rainSensorPin = A0; const int soundDetectorPin = A1; const int buzzerPin = 3; const int servoMotorPin = 9; const int speakerPin = 11; // Variables int rainSensorValue; int soundDetectorValue; Servo servoMotor; void setup() { // Initialize pin modes pinMode(rainSensorPin, INPUT); pinMode(soundDetectorPin, INPUT); pinMode(buzzerPin, OUTPUT); pinMode(speakerPin, OUTPUT); servoMotor.attach(servoMotorPin); } void loop() { // Read sensor values rainSensorValue = analogRead(rainSensorPin); soundDetectorValue = analogRead(soundDetectorPin); // Check if it's raining if (rainSensorValue > 500) { // Stop swinging and turn off sound servoMotor.write(90); noTone(speakerPin); // Turn on buzzer to indicate error digitalWrite(buzzerPin, HIGH); delay(500); digitalWrite(buzzerPin, LOW); } else { // Check if baby is crying if (soundDetectorValue > 500) { // Start swinging and play lullaby servoMotor.write(0); tone(speakerPin, 440); } else { // Stop swinging and turn off sound servoMotor.write(90); noTone(speakerPin); } } }
This code reads the analog inputs from the rain sensor and sound detector, and uses them to control the servo motor and play sounds through the speaker and buzzer. The servo motor swings the cradle if the sound detector detects crying, and stops if the rain sensor detects rain or if the baby stops crying. If there is an error, such as a malfunctioning sensor, the buzzer will sound.
Note that this is just a basic example and you may need to adjust the code and add more functionality to suit your specific needs.
To stop the buzzer, you can add a digitalWrite statement to turn off the buzzer pin. Here is an updated sample code that includes this:cant stop the buzzer
#include <Servo.h>

// Initialize pin modes
pinMode(rainSensorPin, INPUT);
pinMode(soundDetectorPin, INPUT);
pinMode(buzzerPin, OUTPUT);
pinMode(speakerPin, OUTPUT);
servoMotor.attach(servoMotorPin);
}
void loop() {
// Read sensor values
rainSensorValue = analogRead(rainSensorPin);
soundDetectorValue = analogRead(soundDetectorPin);
// Check if it's raining
if (rainSensorValue > 500) {
// Stop swinging and turn off sound
servoMotor.write(90);
noTone(speakerPin);
// Turn on buzzer to indicate error
digitalWrite(buzzerPin, HIGH);
delay(500);
digitalWrite(buzzerPin, LOW);
}
else {
// Check if baby is crying
if (soundDetectorValue > 500) {
// Start swinging and play lullaby
servoMotor.write(0);
tone(speakerPin, 440);
}
else {
// Stop swinging and turn off sound
servoMotor.write(90);
noTone(speakerPin);
digitalWrite(buzzerPin, LOW); // Turn off buzzer

}
}
code for automatic baby cradle usingTo stop the buzzer, you can add a digitalWrite statement to turn off the buzzer pin. Here is an updated sample code that includes this:
Code:#include <Servo.h> // Pin connections const int rainSensorPin = A0; const int soundDetectorPin = A1; const int buzzerPin = 3; const int servoMotorPin = 9; const int speakerPin = 11; // Variables int rainSensorValue; int soundDetectorValue; Servo servoMotor; void setup() { // Initialize pin modes pinMode(rainSensorPin, INPUT); pinMode(soundDetectorPin, INPUT); pinMode(buzzerPin, OUTPUT); pinMode(speakerPin, OUTPUT); servoMotor.attach(servoMotorPin); } void loop() { // Read sensor values rainSensorValue = analogRead(rainSensorPin); soundDetectorValue = analogRead(soundDetectorPin); // Check if it's raining if (rainSensorValue > 500) { // Stop swinging and turn off sound servoMotor.write(90); noTone(speakerPin); // Turn on buzzer to indicate error digitalWrite(buzzerPin, HIGH); delay(500); digitalWrite(buzzerPin, LOW); } else { // Check if baby is crying if (soundDetectorValue > 500) { // Start swinging and play lullaby servoMotor.write(0); tone(speakerPin, 440); } else { // Stop swinging and turn off sound servoMotor.write(90); noTone(speakerPin); digitalWrite(buzzerPin, LOW); // Turn off buzzer } } }
In this code, the buzzer pin is set to LOW to turn it off when the baby stops crying and the cradle stops swinging. This should stop the buzzer from sounding continuously.

code move servo motor when a sound detected by a microphone in arduinoTo create an automatic cradle that moves when it detects a baby crying, you will need to write a program for your Arduino that uses a microphone to detect sound levels and a servo motor to control the movement of the cradle.
Here is an example code that you can use as a starting point:
Code:#include <Servo.h> // Define pins const int microphonePin = A0; const int servoPin = 9; // Define variables int threshold = 500; // Adjust this value to set the sensitivity of the microphone int currentLevel = 0; int previousLevel = 0; Servo myServo; void setup() { // Initialize servo myServo.attach(servoPin); // Initialize serial communication Serial.begin(9600); } void loop() { // Read microphone level currentLevel = analogRead(microphonePin); // Check if sound level has exceeded threshold if (currentLevel > threshold && previousLevel <= threshold) { // Baby is crying, move cradle Serial.println("Baby is crying, moving cradle"); myServo.write(90); // Move servo to 90 degrees delay(2000); // Wait 2 seconds myServo.write(0); // Move servo to 0 degrees } // Save current level as previous level previousLevel = currentLevel; // Wait a short amount of time before repeating loop delay(20); }
This code uses theanalogRead()
function to read the sound level from the microphone, and checks if it has exceeded a certain threshold value (threshold
). If the sound level is above the threshold and the previous sound level was below the threshold, the program moves the servo to a position that will rock the cradle.
Note that you may need to adjust the threshold value to suit your specific microphone and environment. You can also adjust the delay values to change the amount of time that the cradle moves.
#include <Servo.h>
Servo myservo;
const int soundPin = A0; // Analog input for microphone
int soundValue = 0; // Store sound level
int threshold = 500; // Set threshold level for detecting sound
void setup() {
myservo.attach(9); // Attach servo to pin 9
Serial.begin(9600); // Initialize serial communication
}
void loop() {
soundValue = analogRead(soundPin); // Read sound level from microphone
Serial.println(soundValue); // Print sound level to serial monitor
if (soundValue > threshold) { // If sound level is higher than threshold
myservo.write(90); // Move servo to 90 degrees
delay(1000); // Wait for 1 second
myservo.write(0); // Move servo to 0 degrees
delay(1000); // Wait for 1 second
}
}
#include <Servo.h>
Servo myservo;
int soundSensor = A0;
int soundThreshold = 500;
int servoPos = 0;
int servoStep = 1;
void setup() {
myservo.attach(9);
pinMode(soundSensor, INPUT);
}
void loop() {
int soundValue = analogRead(soundSensor);
if (soundValue > soundThreshold) {
if (servoPos == 0) {
servoStep = 1;
} else if (servoPos == 180) {
servoStep = -1;
}
servoPos += servoStep;
myservo.write(servoPos);
delay(10);
}
}
servoStep
variable is used to determine the direction of the movement. The delay
function is used to slow down the movement of the servo motor. soundThreshold
value to suit your particular sound sensor.swing servo motor back and forth when sound is detected by sound sensorHere is an example code for Arduino that moves a servo motor back and forth when sound is detected by a sound sensor:
Code:#include <Servo.h> Servo myservo; int soundSensor = A0; int soundThreshold = 500; int servoPos = 0; int servoStep = 1; void setup() { myservo.attach(9); pinMode(soundSensor, INPUT); } void loop() { int soundValue = analogRead(soundSensor); if (soundValue > soundThreshold) { if (servoPos == 0) { servoStep = 1; } else if (servoPos == 180) { servoStep = -1; } servoPos += servoStep; myservo.write(servoPos); delay(10); } }
This code first sets up a Servo object and initializes the sound sensor pin and threshold. In the loop function, it reads the sound sensor value and checks if it is above the threshold. If it is, it moves the servo motor back and forth between positions 0 and 180. TheservoStep
variable is used to determine the direction of the movement. Thedelay
function is used to slow down the movement of the servo motor.
Note: This code assumes that the sound sensor outputs an analog value between 0 and 1023. You may need to adjust thesoundThreshold
value to suit your particular sound sensor.
