having an external button control the media player.

Hello Gordon,

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

https://www.espruino.com/BLE+Music+Control

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) {
    controls.next();
    digitalPulse(LED1,1,100);
  } else {
    controls.playpause();
    digitalPulse(LED2,1,100);
  }
}, BTN, { edge:"falling",repeat:true,debounce:50});

Hi! Since you're using a Puck, the pin names are a bit different (starting with D... and not Ax/Bx/etc) but yes what you're suggesting is fine apart from that.

I'd say just connect a button between maybe pin D1 and the 3v pin (this means you don't need digitalWrite(A6, 1);/similar because the pin is already at a voltage).

Then it's just:

pinMode(D1, 'input_pulldown');
setWatch(function(e) {
  controls.playpause(); // or whatever else you want to do
}, D1, { repeat: true, edge: 'rising', debounce: 50 });

// your other HID code here...

Wow Gordon, thank you so much! I bought you a coffee with the donate button. Much appreciated.

Thank you! Did it work ok?

Perfectly! Thank you so much!!! 🙏
