Hit problem with REMOTE CONTROL SOCKETS 433hz tutorial

I have the same receiver and transmitter as on this image:
After some tests I found that left one on the image is the transmitter (3 pins) and right one is the receiver (4 pins)

I using the code from example, here are my exact code with connections:

/**
  On press button BTN1 send bits (CODE variable) from transmitter (A1) to receiver (A0) multiple times. Blue LED blinking on send data, green LED blinking on receive data.
  
  Transmitter:
    GND <-> GND
    VCC <-> Bat
    ATAD <-> A1
    
  Receiver:
    GND <-> GND
    VCC <-> 3.3 (If using Bat there are many errors that we get on input)
    DATA1 OR DATA2 <-> A0
*/

var t,n, counter = 0;

// When the signal rises, check if it was after ~5ms of delay - if so (and if we have a code) display it.
function sigOn(e) {
 // console.log('sigOn:', getTime());
  var d = e.time-t;
  if (d>0.005 && n>0) {
    console.log(counter++, ":0b"+n.toString(2));
    n=0;
  }
  t = e.time;
  LED2.write(1);
}

// When the signal falls, measure the length of our pulse. 
// If it was within range, record a 1 or a 0 depending on the length. 
// If it wasn't in range, zero it
function sigOff(e) {
 // console.log('sigOff:', getTime());
  var d = e.time-t;
  t = e.time;
  if (d>0.0001 && d<0.001)
    n = (n<<1) | ((d>=0.0004)?1:0);
  else
    n=0;
  LED2.write(0);
}

setWatch(sigOn,A0,{repeat:true,edge:"ris­ing"});
setWatch(sigOff,A0,{repeat:true,edge:"fa­lling"});

var TX = A1;
var CODE = 0b10100000111111101110;

function sendCommand(command) {
  LED3. write(1);
  var bits = (CODE & ~0b11111) | command;
  for (var i=24;i>=0;i--) {
    if ((bits>>i)&1) {
      digitalPulse(TX,1,0.9);
      digitalPulse(TX,0,0.3);
    } else {
      digitalPulse(TX,1,0.3);
      digitalPulse(TX,0,0.9);
    }
  }
  digitalPulse(TX,1,0.001);
  LED3. write(0);
}

function sendMultiple(command) {
  var n = 9;
  var interval = setInterval(function() {
    sendCommand(command);
    if (n-- < 0) clearInterval(interval);
  }, 50);
}

var socketOn = false;
setWatch(function() {
  socketOn = !socketOn;
  sendMultiple(socketOn ? 0b11110 : 0b01110);
}, BTN1, { repeat:true, edge:"rising", debounce:10 });


// A1 -> transmitter (3 wires) green
// A0 -> receiver (4 wires) yellow

Hope this helps, LMK if you need some help, I passed it before few days. :)

BTW, how did you checked the remote control that it works fine?

PS: Here is additional good explanation for the code if you need it.
