TimerOne Library

Hello,

I am building my fist Arduino project using Krida Light dimmer PCB. For this project I am trying to utilize an existing Arduino code which includes <TimerOne.h> Library. However, I cannot find TimerOne library anywhere. Only CurieTimerOne library.
Anyone out there could suggest where do I find TimerOne.h library ?

Thank you !

Try this. . There are several ways to get to it from the first few links.

Thank you Delta-G !
I'm not sure why I came up empty handed when I tried to search for it...
