I have installed Arduino IDE v1.6.8 and trying to code Adafruit FLora board , but am not able to see the option Adafruit FLora board under board manager option. I also watched link saying how to add third party boards in arduino ide , but when i try to follow that , there is no option to select third party boards ("contributed" as mentioned in the link).
Please help me out from this problem as I am stuck at initial step and not able to go ahead with the work.
I don't know. I did not have trouble adding the boards to my IDE using the links I gave. I suggest make sure you put the right URL for Additional Boards Manager URLs in the IDE preferences panel. Perhaps you could show some screen shots of your IDE Preferences panel and Boards Manager panel to show us what you see.
You can also search in the Adafruit forum to see if others have the same trouble and what they did to fix.
I hope you have installed the necessary driver required for Windows before using Flora. Also after putting the right URLs, when you plugin your flora, it should come in the boards...
