Arduino House

I created a house with a light that gradually turns on a light if it is dark and an alarm connected to the door.

 BLYNK comments
 
 * 1. Optional, but recommended.
 *    Connect additional USB-serial adapter to see the prints.
 *
 * 2. Edit auth token and upload this sketch.
 *
 * 3. Run the script (script located in "scripts" folder of library root,
 *    e.g. 'blynk-library/scripts') for redirecting traffic to server:
 *
 *      for Windows:
 *                     1. Open cmd.exe
 *                     2. write : (your way to blynk-ser.bat folder) example: "cd C:\blynk-library-0.3.1\blynk-library-0.3.1\scripts"
 *                     3. write : "blynk-ser.bat -c COM4" (where COM4 is port with your Arduino)
 *                     4. And press "Enter" , press "Enter" and press "Enter"
 *
 *      for Linux and OSX:
 *
 *                    ./blynk-ser.sh (may need to run with sudo)
 *
 *    You can specify port, baud rate, and server endpoint like this:
 *      ./blynk-ser.sh -c <serial port> -b <baud rate> -s <server address> -p <server port>
 *
 *    For instance :
 *      ./blynk-ser.sh -c /dev/ttyACM0 -b 9600 -s blynk-cloud.com -p 8442
 *
 *    Run blynk-ser.sh -h for more information
 *
 *    Be sure to select the right serial port (there may be multiple).
 *
 *    Attention!
 *        Arduino IDE may complain with "programmer is not responding".
 *        You need to terminate script before uploading new sketch.
 *
 * 4. Start blynking! :)
