ESP8266-01 Blink Example Schematic with Arduino

Hello guys, I'm trying to test my ESP8266 with example of Blink from ESP8266 file but I don't know the schematic. I've been searching all day but couldn't find anything. Code will be;

int ledState = LOW;

unsigned long previousMillis = 0; const long interval = 1000;

void setup() { pinMode(LED_BUILTIN, OUTPUT); }

void loop() { unsigned long currentMillis = millis(); if(currentMillis - previousMillis >= interval) { previousMillis = currentMillis; if (ledState == LOW) ledState = HIGH; // Note that this switches the LED off else ledState = LOW; // Note that this switches the LED on digitalWrite(LED_BUILTIN, ledState); } }

Can someone show me the schematic?

Thanks in advance!

Thank you so much but this is still a bit complicated for me. :) Is there any schematic for me to easy to understand?

Thank you.

The ESP-01 is a little tricky to use because it only has two GPIO pins (GPIO0 and GPIO2) and the settings on those two pins effect whether the module is running the sketch or whether you will be uploading a new sketch. This is explained in Chapter 4 of Pieter's tutorial paragraph Boot Modes. describes "tricks" on how to use the ESP-01.
