Hey,
i tested the other controller, on receiving data, and it is a little bit frustrating. Above, the description don`t works on this controller.

For this pulse:

  var pulse = [0.6, gap, 1.0, gap, 0.6, gap, 1.0, gap, 1.0, gap];

i get this console.log:

1011

I don`t know, where the problem is and which controller will be right....puh

I used a normal IR LED and a vs1838b

Sry, i don`t have an oscilloscope :(
best regards

Hey,
thanks for your really good support. The LED is connected in right way. That was the first, what i checked. But it was a really nice thinking :)
Yesterday, i tested a little bit and solve the problem. The solution is (for me) confusing and i don`t know the technical details.

Sending a zero:

[1.0, gap]

Sending a 1:

[gap, 1.0]

and as last bit for end of transmitting:

[gap]

If you send no 'gap' as last, it won`t be shown the string in the console.

Complete code for sending '101001':

digitalWrite(B7, 0); // Set B7 to GND
digitalWrite(A8, 1); // Set A8 to 3.3V
// Because we're not using the module, we have to manually pull up the data pin
pinMode(B6,"input_pullup");

setInterval(function(){
  
  var gap = 0.5;
//  var pulse = [0.6, gap, 0.6, gap, gap, 2.0, gap, gap, 0.6];
    var pulse = [gap, 1.0, 1.0, gap, gap, 1.0, 1.0, gap, 1.0, gap, gap, 1.0, gap];

  digitalWrite(LED1,1);
  
  analogWrite(A5, 0.9,{freq:38000});
  
  digitalPulse(A6, 1, pulse);
  
  digitalPulse(A6, 1, 0);
  
  digitalWrite(LED1,0);
},1000);

Hi,

thanks for your answer. It was very helpful. Now i tested with the follow code:

Transmitter:

digitalWrite(B7, 0);
digitalWrite(A8, 1); 
pinMode(B6,"input_pullup");

setInterval(function(){
  
  var gap = 0.5;
  var pulse = [1.0, gap, 1.0, gap, 0.6, gap, 1.0];
  
  digitalWrite(LED1,1);
  
  analogWrite(A5, 0.9,{freq:38000});
  
  digitalPulse(A6, 1, pulse);
  
  digitalPulse(A6, 1, 0);
  
  digitalWrite(LED1,0);
},1000);

and Receiver code:

digitalWrite(B7, 0); 
digitalWrite(A8, 1); 

require("IRReceiver").connect(B6, function(code) {

  console.log(code);
  
  if(code === '0010') digitalWrite(LED2, 1);
  
});

I get every time a '000' in the console and no LED will be switched on. Sometimes an '0001'. Is there way to transmit correctly or did i something wrong?

Sry.

Hey,
thanks for your reply. For correct understanding:

If i use Gordon`s IRReciever (what i want), and sending a logical 1, i have to use at first:

analogWrite(A5,0.9,{freq:38000});

and than:

digitalPulse(A6, 1, 1);

and for a logical 0:

digitalPulse(A6, 1, 0.8); //or less

?

In my mind so i have to send '110':

digitalPulse(A6, 1, [1,1, 0.8]);

sry for my nooby question/post, but i only want to understand.

Hi@all,

i recieved 2 Picos and they are great. For Project, both have to communicate together over infrared. I have tested this tutorial . Receiving tv remote signals is no problem. But i have trouble with sending data. I want to send my own data like '10001111'. How can i do this? Have anyone an idea? I hope you can help me.

best regards
daniel
