Setting up Huzzah ESP8266 I am trying to set up a Huzzah ESP8266 and can not get it to work. I have scoured the internet for help and to no avail. I have the board loaded with a baud rate of 115200 and am transmitting at  80 MHz. When I try and upload the sketch it successfully uploads and after a second or two it sends me this error.


  Sketch uses 222,209 bytes (21%) of program storage space. Maximum is
  1,044,464 bytes. Global variables use 31,576 bytes (38%) of dynamic
  memory, leaving 50,344 bytes for local variables. Maximum is 81,920
  bytes.
  
  warning: espcomm_sync failed
  
  error: espcomm_open failed
  
  error: espcomm_upload_mem failed
  
  error: espcomm_upload_mem failed


Here is my code:

 void setup() {
pinMode(LED_BUILTIN, OUTPUT);     // Initialize the LED_BUILTIN pin as an output
}

// the loop function runs over and over again forever
 void loop() {
digitalWrite(LED_BUILTIN, LOW);   // Turn the LED on (Note that LOW is the    voltage level
                                // but actually the LED is on; this is     because 
                                // it is acive low on the ESP-01)
delay(1000);                      // Wait for a second
digitalWrite(LED_BUILTIN, HIGH);  // Turn the LED off by making the voltage HIGH
delay(2000);                      // Wait for two seconds (to demonstrate the active low LED)
}


Does anyone know what I'm doing wrong or can anyone help me out.
If you´re working with a development board, they (usually) come with tow buttons: Reset and Flash. If this is the case before start to upload your code you must press the Flash button, this error is common when the Flash button it's not pressed. 

If you're working with an ESP8266-01 (this is the "naked" esp8266) you must read this tutorials: GreatScott vid on youtube, and for the connections: a good Hackster.io tutorial.

Hope you can make it run!!!
