Assume, you have an Espruino Pico, and you have added a button on pin B3 to 3.3V, you proceed as follows:
```
pinMode(B3,"input_pulldown");
var SWBtn = require("SWButton");
  , mySWBtn = new SWBtn(function(k){
    console.log("Btn on B3 detected " + k); // log key press pattern
  },B3);
```
mySWBtn is now working on pin B3. You need to set the pin mode, otherwise you do not get predictable results, because you put a watch on a float.

PS: above example assumes also that you download / copy-paste the SWButton code from url on git into your modules folder with the name WSButton.js. You can of course keep the url in the require(...).

i have espruino Original, and with code I placed above it is not working with button installed on board, I can call this button from IDE by BTN and BTN1 (and button works with other examples), but not with the code I placed above

i also try it like this, and still doesn't work

pinMode(B12,"input_pulldown");//i understand B12 is corresponding to BTN or BTN1 on espruino code

var SWBtn = require("https://raw.githubusercontent.com/muet/EspruinoDocs/master/modules/SWButton.js");

var mySWBtn = new SWBtn(function(k){
    console.log("Btn on B3 detected " + k); // log key press pattern
  },B12);
