- Sat Jun 24, 2017 11:21 am #67537 Hi I'm new to esp8266.

I saw an example for arduino uno where you can display on screen the signal received from your tv remote. I wanted to build the same thing using NODEMCU, but I'm not having any luck with it. here's the code I'm using:

Code: Select all#include <IRrecv.h>

int RECV_PIN = 14;

IRrecv irrecv(RECV_PIN);

decode_results results;

void setup()
{
  Serial.begin(9600);
  irrecv.enableIRIn();
}

void loop() {
  if (irrecv.decode(&results)) {
    Serial.println(results.value);
    irrecv.resume();
  }
}


Here's the error message i get:
