 # Arduino Ticker Library v3.0
 
-The **Arduino Ticker Library** allows you to create easily Ticker callbacks, which can call a function in a predetermined interval. You can change the number of repeats of the the callbacks, if repeats is 0 the ticker runs in endless mode. Works like a "thread", where a secondary function will run when necessary. The library use no interupts of the hardware timers and works with the **micros() / millis()** function. You are not (really) limited in the number of Tickers.

 ## New in v2.0
 - You can determine the number of repeats, instead of modes.
