+
+RGB led blinking through website
+
+Python + Arduino project.
+
+## Installation
+1) Download Arduino IDE and python3.x
+2) Upload StandardFirmata.ino code in arduino
+3) Install python3.X and libraries in requirements.txt
+
+``` pip3 install -r requirements.txt```
+
+
+## Circuit of Arduino
+
+*  Pin 2 = Positive terminal of buzzer
+*  Pin 3 = Red terminal of rgb light
+*  Pin 4 = Green terminal of rgb light
+*  Pin 5 = Blue terminal of rgb light
+*  GND   = Negative terminal of buzzer
+*  5V    = Cathode point of RGB light
+
+## Execution
+*	Connect arduino with your system
+*	Open file StandardFirmata.ino and upload the folder
+*	Open the folder of code
+*	Open terminal in that folder
+*	Enter folder code into terminal and hit enter
+```
+flask run -h 0.0.0.0
+```
+*	Open any device that is connected to same network or wifi
+*	Open the url (printed in the terminal)
+*	Enjoy!!
+
+### Note:-	
+Make sure you have connected the laptop and the mobile with same network or wifi
+
+## Uses
+*	This can be used as an application in smart home system, where your can turn on and off appliances according to your will thorugh your mobile phone or devices connected under home network.
+*	This can be used in smart office, where your can turn on and off office lights, systems ...etc according to your will thorugh your mobile phone or devices connected under home network.
+*	This can be used as an application in smart class, where your can turn on and off hall lights according to your will thorugh your mobile phone or devices connected under home network.
