## Environments and Tools
### 1.Hardwares
* Raspberry Pi 3B
* PCA9685
* Servo Motor *2
* PIR
* Picamera v2
* 3.5mm Speaker
### ==how to set your PCA9685==
* PCA9685 must have 6v power to let the servo motor to move successfully
* servo motor on the tail connect to PCA[0]
* servo motor on the mouth connect to PCA[1]
* first install the adafruit library

sudo pip3 install adafruit-circuitpython-servokit

* VCC connect to PIN1
* SDA connect to PIN3
* SCL connect to PIN5
* GND connect to PIN9

### ==how to set your PIR==
* VCC connect to PIN2
* GND connect to PIN6
* GPIO connect to PIN26

### 2.Environment
* Raspberry Os
* OpenCV 3.2.0
* GCC v7.1
* Python 3.7

### ==how to build the OpenCV environment==
* Update the system

    sudo apt-get update
    sudo apt-get upgrade
    sudo rpi-update
    sudo reboot

* Install tools

    sudo apt-get install build-essential cmake cmake-curses-gui pkg-config vim

* v4l Library

    sudo apt-get -y install libv4l-dev v4l-utils

* activate core model

    sudo modprobe bcm2835-v4l2

* test the model

    v4l2-ctl --list-devices

* Other libraries

    sudo apt-get install libatlas-base-dev gfortran

* Install Python-Dev & Numpy

    sudo apt-get install python3-dev python3-numpy

* DownLoad OpenCV source packages

    mkdir /home/pi/Download/opencv
    cd  /home/pi/Download/opencv
    wget https://github.com/opencv/opencv/archive/3.2.0.zip -O opencv_source.zip
    wget https://github.com/opencv/opencv_contrib/archive/3.2.0.zip -O     opencv_contrib.zip

* unzip the code

    cd /home/pi/Download/opencv
    unzip opencv_source.zip
    unzip opencv_contrib.zip

* make build folder

    cd /home/pi/Download/opencv/opencv-3.2.0
    mkdir build
    cd build

* init the configuration and Cmake

    cmake -D CMAKE_BUILD_TYPE=RELEASE \
     -D CMAKE_INSTALL_PREFIX=/usr/local \
