• Hello Gordon,

    I have successfully set up the puck.js to control Music player via BLE as your cool project available at


    I would like to now do the same thing with an external button attached to the puck.

    In another forum post, you said this was possible using the methods here:


    I see that I can connect the external switch between to io buttons (e.g. A6 and B1) and that I dont need to use an external resistor for this.

    I am unsure of the code to use. Do I just paste your two sets of code together (as I have done below - is it correct)? Or do I need to change some of the BTN lines?

    Thanks very much for your help...


    digitalWrite(A6, 1);
    pinMode(B1, 'input_pulldown');
    setWatch(function(e) {
      console.log("Button pressed");
    }, BTN, { repeat: true, edge: 'rising', debounce: 50 });
    // you'll need to use  edge: 'falling' if you connected the button to 0v
    var controls = require("ble_hid_controls");
    NRF.setServices(undefined, { hid : controls.report });
    setWatch(function(e) {
      var len = e.time - e.lastTime;
      if (len > 0.3) {
      } else {
    }, BTN, { edge:"falling",repeat:true,debounce:50})­;
