My Home1000 Holiday Things for HOME Automation & Control

Remotely we control our home with MKR1000 and IOT of Blynk. We can manage the boiler, the ‘anti-theft irrigation, open the Automatic Gate.

The project was born from me and my son for the competition Arduino Internet of Holiday Things, who declined to be able to turn on remote heating the house or the garden lights or christmas lights and operate the alarm, and while the holidays? Here ‘IOT and MKR100 possible and even easy and low cost. Now I will explain how to proceed.




My Home1000 Holiday

Here’s your first circuit diagram …
And in the process of development and improvement


 * Blynk is a platform with iOS and Android apps to control
 * Arduino, Raspberry Pi and the likes over the Internet.
 * You can easily build graphic interfaces for all your
 * projects by simply dragging and dropping widgets.
 *   Downloads, docs, tutorials:
 *   Blynk community:  
 *   Social networks:  
 * Blynk library is licensed under MIT license
 * This example code is in public domain.
 * This example shows how to use Arduino MKR1000
 * to connect your project to Blynk.
 * NOTE: You may need to install WiFi101 library through the
 *       Arduino IDE Library Manager.
 * Feel free to apply it to any other example. It's simple!

   Wire.begin(); // required by BMP180
    timer.setInterval(1000L, sendSensor);

// This function will be called every time
// when App writes value to Virtual Pin 1
     digitalWrite(caldaia, LOW);
     digitalWrite(caldaia, HIGH);
