"Twist" Music Control

Hey there,

first of all, thanks to everyone who created Bangle.js. Without this piece of hard- and software I would've never started to try writing code.
In the last two days I tried to write an app (never wrote any code before, I hope it's not too "ugly") to control a music player on Android, which can be controlled by multiple play-commands (1x play / 2x next song / 3x previous song / 4x next folder / 5x previous folder), by a twist of your arm. The idea behind this was: there may be situations when you second hand isn't free, but you wanna change the song you're listening to.

I had some problems, which I solved very intricately (is this the right word? I'm no native english speaker :sweat_smile: ) I guess.

Maybe somebody wants to take a look and tell me how to handle things better or less intricate?

/////////////////////////////////////////////////////////////
//   control music by twist/buttons

let counter = 0;
var tstate = false;

// defining commands
function playx() {
  Bluetooth.println(JSON.stringify({t:"music", n:"play"}));
}

function volu() {
  Bluetooth.println(JSON.stringify({t:"music", n:"volumeup"}));
}

function vold() {
  Bluetooth.println(JSON.stringify({t:"music", n:"volumedown"}));
}

function resetc() {counter=0;}

function cstate() {
  tstate=!tstate;
  setTimeout(resetc,100);
  Bangle.beep(200,3000);}

function countup() {
  if (counter < 5){
    counter++;
    Bangle.buzz(100,2);
    }
  else {counter = 0;
        Bangle.buzz(400);
       }
}

function sendCmd() {
  print (counter);
  Bangle.removeListener('twist',countup);
  if (tstate==false && counter>0){
  do {playx(); counter--;}
  while (counter >= 1);
  }
}

function twistcount() {
  if (tstate==true){
  Bangle.on('twist',countup);
  }
}

function twistctrl() {
  if (tstate==false)
  {cstate();
  twistcount();
  setTimeout(cstate,4000);
  setTimeout(sendCmd,4100);
  }
}

setWatch(volu,BTN1,{repeat:true});
setWatch(vold,BTN3,{repeat:true});
Bangle.on('twist',twistctrl);
setWatch(Bangle.showLauncher, BTN2, {repeat:false,edge:"falling"});

Is this the right place for this thread, or is "Projects" the better place?
