 Creates a Ticker object
 - parameter callback for the function name you want to call
-- parameter interval sets the interval time in ms
-- parameter interval resolution can changed to us instead of ms with setting the parameter resolution to MICROS_MICROS

 - parameter repeats sets the number of repeats the callback should executed, 0 is endless
 - parameter resolution sets the internal resolution of the Ticker, it can MICROS, MICROS_MICROS or MILLIS
