Introduction: Crying Baby Detector Using 1Sheeld

Picture of Crying Baby Detector Using 1Sheeld

The biggest problem that mothers face is that they can't leave their babies alone in a room asleep, That they must sit next to them, And leave anything else in there hand because getting afraid if the baby starts to wake up which is a wasting of time, From there came my IDEA

Crying Baby Detector is a project taken from Baby Monitor concept but the differences are that my idea take some ACTIONS like automatic playing music for the baby So that the baby get back to sleep , Using what's called White Noise which is some quiets noise or music that comfort the baby which get him/her back to sleep , And if the baby doesn't get back to sleep , it starts playing more louder music so that the baby feel safe.

Step 2: Downloads

Step 3: Installing the Library & Installing the App on Android

Picture of Installing the Library & Installing the App on Android

Installing the library:

1-open the Arduino ADK

2-open sketch then Import library then add the library

3-Choose the zip file from where you downloaded

Installing the App on Android:

After downloading the app ,open it and search for the 1Sheeld and connect it , then choose the needed shield (Mic-MusicPlayer-Twitter)
,Then log in with Twitter, and Choose the tracks for MusicPlayer , I made 2 tracks one for SleepingMode (Quiet music) and the other for WakingMode (Children songs)

Step 4: Code

In this code I wrote in different style,I wrote it from downside to upside ,I had 3 Functions (1-SleepingMode1())-(2-SleepingMode2())-(3-WakingMode()) ,I wrote the third at first , then the second then the first

SleepingMode1: if the Baby starts crying the arduino starts playing some quiet Music

SleepingMode2: if the baby didn't stop crying the arduino continue playing the quiet music

In all these functions arduino send to the parents message on the twitter to inform them any updates

include<one.sheeld.h>
String account = "imtheparent2015";// The parent account on twitter
String Message0 ="Arduino Now is on Monitoring Mode , Stay tuned for any updates";
String Message1 = "The baby is crying ,The Arduino is on SleepingMode right now stay Tuned For any updates";// The Arduino message for the parent at the Sleeping Mode
String Message2 = "The baby is awake ,The Arduino is on WakingMode right now , and playing some songs";// The Arduino message for the parent at the Waking Mode
String Message3 = "The baby is now asleep ,You Are Safe :D";// The Arduino message for the parent at the Sleeping Mode
String Message4 ="The Baby is still crying ,Stay tuned for any updates";

Step 5: Circuits & Soldering All the Components

Picture of Circuits & Soldering All the Components

I didn't solder the components on a board ,I solder them togther to minmize the size to be easy put in the toy but it's up to you, you can solder it on a board

after soldering put the relay circuit in the toy and connect the relay to the battery of the toy one at (COM) and the other at (NO) of the relay

After finishing the toy circuits you will have three wire (+5V-GND-Arduino output) connect those to the arduino

And you are ready to GO.....

Step 6: Ready to GO

Picture of Ready to GO

Now you are ready just turn on the Arduino and open the app and scan for devices it will connect automatically ,Just put the your phone next the baby and GO WATCH A MOVIE YOU ARE SAFE :D

So, did the arduino successfully played the music and your baby slept?

This is great! I love the idea of an automated baby monitor!
