What was happen?
I moved your topic to an appropriate forum category @ayrawn.
In the future, when creating a topic please take some time to pick the forum category that best suits the subject of your topic. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is an important part of responsible forum usage, as explained in the "How to get the best out of this forum" guide. The guide contains a lot of other useful information. Please read it.
Thanks in advance for your cooperation.
You will need to label all your devices and all the connections and post a readable, understandable image of the wiring diagram. You will also need to post your formatted code.
Possible causes are; wiring, code, insufficient power supply.
