The Internet of Holiday Lights
(The Santa monitor & lights - part-2)
Hello again folks and Mary Christmas to you all! In this part i'm going to speed up things a little bit and go to the second stage of the challenge and build the first objective - windows and aquarium/vibe lamp lights. So far i've tested and installed almost 5m of RGB strip with one Arduino UNO + one Infineon RGB shield with the Dave's examples on I2C protocol (with a bit of tweaking on the delays and maximum light values) on my window.
This is the Dave's code for arduino UNO and Infineon RGB shield with minor tweaks from line 170 to 199 to work with simple RGB and get 6 colours:
// Infineon RGB_LED_Shield_Master_Tester
// by Michelle Chia
// Demonstrates I2C communication with the RGB LED Shield for safe configuration. Tested at 48Vin, 6V forward voltage LED. LED current up to 350mA.

}In the first part i've presented to you, Arduino YUN + Infineon RGB shield and MQTT server library, for a remote manual control of an application, with a javascript html application developed by kartben
Controlling Holiday Lights using MQTT and the Arduino Yún and Infineon RGB shield
Now i have an automated lighted window and still working on a lighted lamp too (ah wires all over 
). By tweaking, you can obtain combination of colours and timings, from a simple RGB led strip (obtained 6 colours in total : base colours > red, blue, green and combined colours > cyan, magenta and yellow from combining each two colours from the first three).
The third and hopefully final stage, will represent the sensor array and the music conditioned by them. The "hohoho" sounds on a proximity sensor, and the "chillout carol" sounds if it snows. Stay tuned till then...i'll be back shortly with interesting feeds. Till then, here's a demo of the second part with only 3 colours:
View from inside:
P.S. - oh yeah, and flowers .
View from outside:
...and a dog 
.
Please enjoy!
