Ticker is an interrupt driven time interrupt. A ticker works like a kitchen timer, you set it up to tick down from some value in seconds, when it reaches 0 it calls a callback function, then resets the ticker and starts the whole process over again. A ticker can be used to cause periodic events, like blinking an LED on and Off at a certain rate. A tickers maximum time it can handle is 30min, for anything greater consider using the real time clock functionality.
