Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Component Used for This Project
1 - Arduino Uno (or any type of Arduino family).
2 - 1Sheeld .
3 - application of the shield and a smartphone .
4 - LEDs .
5 - ultrasonic .
6 - breadboard .
7 - wires .
Step 2: Get Start the Project
first you must download the shield app from this link on you smartphone
the library of the shield
how to get start with the 1shield
this security system can be used to detect if someone has entered your home after entering the password wrong for 3 times .
if the password has be entered 3 times wrong the shield will send a message to your mobile alarm you that there is someone try to enter your home .
the ultrasonic will detect if someone had already entered the home or not ,if yes the shield will post on your facebook timeline to get help from your neighbors .
Step 3: Arduino Code and Hardware
connection will be as the image below
/* Arduino cade */
Step 4: Project Simulation
when you enter the password (1234) the led blink and the terminal show that the entered password
one is pressed
two is pressed
three is pressed
four is pressed then... welcome home
if the password is wrong for the first three digits it will send a message to your mobile and show that also on the terminal
