About this project

Overview

I wanted to automate various aspects of my Christmas tree, namely the lights. I also wanted to know if there is any activity around the tree. This could include someone peeking too early at a present, or even when Santa Claus arrives. I have an IP camera pointed at the Christmas tree so I can view the activity when motion is detected.

One MKR1000 is location on the Christmas tree (it looks like an ornament!) and the other MKR1000 is located on my office desk. The MKR1000 on my office desk will turn on an alarm light if motion is detected by my Christmas tree at home. I will also receive a text message when motion is detected.

I used the MKR1000 and Cayenne Scheduling to turn my Christmas tree lights on at sunrise and off at sunset.

I used an Arduino MKR1000 with Cayenne IoT Project Builder. Cayenne handled all of the automation, trigger events, scheduling, and text message notifications used in the project.

Here is an overview video I created:

MKR1000 Cayenne Sketch FileC/C++
This sketch file comes as an example when the Cayenne Arudino library is download. Just copy and paste the sketch file into the Arduino IDE and input user auth token along with WiFi credentials.
/*
Cayenne MKR1000 Example

This sketch connects to the Cayenne server using an Arduino/Genuino MKR1000 and runs the main communication loop.

The Cayenne Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.

Steps:
1. Install the Arduino SAMD Boards from the Arduino Boards Manager if you have not done so already.
2. Install the WiFi101 library (https://github.com/arduino-libraries/WiFi101) from the Arduino Library Manager if you have not done so already.
3. Select the Arduino/Genuino MKR1000 board and the correct port in the Arduino IDE.
4. Set the token variable to match the Arduino token from the Dashboard.
5. Set the network name and password.
6. Compile and upload this sketch.

For Cayenne Dashboard widgets using digital or analog pins this sketch will automatically
send data on those pins to the Cayenne server. If the widgets use Virtual Pins, data
should be sent to those pins using virtualWrites. Examples for sending and receiving
Virtual Pin data are under the Basics folder.

// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token[] = "AuthenticationToken";
// Your network name and password.
char ssid[] = "NetworkSSID";
char password[] = "NetworkPassword";

void setup()
{
	Serial.begin(9600);
	Cayenne.begin(token, ssid, password);
}

void loop()
{
	Cayenne.run();
}
