Basic Ticker usage
|
|
|
|
Ticker is an object that will call a given function with a certain period.
|
|
Each Ticker calls one function. You can have as many Tickers as you like,
|
|
memory being the only limitation.
|
|
|
|
A function may be attached to a ticker and detached from the ticker.
|
|
There are two variants of the attach function: attach and attach_ms.
|
|
The first one takes period in seconds, the second one in milliseconds.
|
|
|
|
The built-in LED will be blinking.
|
