  • One question…. 4 Amp power supply? It doesn’t seem enough. For example in the blueSky() function you have: strip_a.setPixelColor(i, 0, 170, 175) over all 300 pixels. My math may be wrong but that seems to work out to over 8 amps assuming 60mA per pixel at full white (255, 255, 255). Is my assumption of 60mA for white incorrect or am I missing something else?

  • Hi, I want to make this by myself but I have WS2811 LED strip and NodeMCU. Can anyone help me?

    States.h File

    Make sure that the “States.h” file in the same folder as the CloudCloud.ino [ https://github.com/sparkfun/IoT_CloudCloud/tree/570fda603d4ebe0294ab029a0ca8a9a0341f6045/Thing/CloudCloud ]. Otherwise, the code will not recognize certain variables and functions that are defined when the code compiles.

  • I’ve built my LED Cloud-Connected Cloud, but I can’t seem to change the led colors. The Blynk app does appear to be connecting to the Spark Thing Board (the ‘led’ screen on my iPhone states when it is not connected. I had to lower the voltage from my adjustable AC adapter to 3V. otherwise, the led lights would just blink. I’ll start messing with the code to see if I can make the lights do something. Any suggestions are appreciated.

  • Hi, there is an error in the CloudCloud Thing code on Github as of 5/12/16. The code uses the variable “time” which is used in another piece of code. It will not compile properly. You can use find and replace in the Arduino IDE. Replace “time” with “time1”. Don’t do a “Find & replace all”, as there is also a “timeout” variable used. Sparkfun, please take some time to go over this tutorial again and make some minor updates, as it is really cool, once it works. The Thing code needs updating, spell checking your “Resorces”, and perhaps a new Fritzing drawing that does not have the resistor/LED strip plugged into what is normally a power bus. The Arduino code runs fine on a Nano v3 board as well. Thanks!

  • Where can I find “states.h”? Arduino 1.6.8 doesnt have it!

    EDIT: Nevermind. Found it!

  • Great project! Dramatic and not too complicated although there are quite a bit of parts to bring together. I’m going to adapt it for my own ARM board so I’ll have to port all the code over. You gave enough detail so that won’t be too bad. Thanks!
