Hackable Christmas Greeting Card
Introduction
Hey! Do you have a Christmas Greeting card? Bored and tired of it? Then this is your post.
In this post we will hack a cool Christmas Greeting Card with the possibility of changing the music, the led color (if you have one RGB) and brightness! All of this with Cayenne IoT to make it controllable with a smart phone! And we can make it also, our alarm clock!
Sneak Peak Video:
What you need before starting the project
Of course you need the materials I said before. You need a Cayenne Account, make one here. Then you need Cayenne Library. Simply search for MKR1000 sample Sketch and connect your board to Cayenne Dashboard.
CODE
/*
Project created by Neoxelox for Hackster.io Arduino Contest 31/12/2016
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.

SCHEMATICS
Assembly
Retire the electronics parts the card has and just fill the greeting card with your electronics, if you have a MKR1000 without headers it will be easier.
Cayenne dashboard
Just put 8 buttons for the songs with Virtual connection and put the pins from V1 to V8. For the LED, in my case I only had a single color LED, go to Actuators>Light>Luminosity and select Digital connection with pin D5.
But you can also put 3 more buttons for changing the color of a RGB LED. If you want to make a Christmas Greeting Card alarm clock just go to Scheduler and make an event which will turn on one of the songs at a certain time.
Songs
The project has 8 Christmas songs, but you can put more. The play system is like this Arduino example but modified: http://www.arduino.cc/en/Tutorial/Melody
Well, as you could see in the video the volume was very low, so I recorded the songs with a microphone:
- Ding Dong Merrily
- God Rest Ye Merry Gentlemen
- O Little Town of Bethlehem
- While Shepherds Watched
- In The Bleak Midwinter
- Hark the Herald Herald Angels Sing
- O come all Ye Faithful
- O Come O Come Emmanuel
