explain more about this new project

 On this project i will be used a Arduino UNO to control the whole system when someone is the piezo sensor it will be send signal to the Arduino UNO and the Arduino will be react to the other component to make this system is more secure.

After the Arduino detect the buzzer and all lamp or bulb will be automatically on around the house.
On this project also using a voltage regulator to maintain the voltage output connect with arduino.

Im already contruct and test the voltage regulator to get the maintain output to connect to the arduino. the voltage is 5V. And relay also used in this project, the relay type i used is relay 12V 4-channel. The relay already has been tested to connect to all the lamp or bulb. The connection bulb/lamp are in parallel.
