/*
ESP8266 BlinkWithoutDelay by Simon Peter
Blink the blue LED on the ESP-01 module
Based on the Arduino Blink without Delay example
This example code is in the public domain
The blue LED on the ESP-01 module is connected to GPIO1
(which is also the TXD pin; so we cannot use Serial.print() at the same time)
Note that this sketch uses LED_BUILTIN to find the pin with the internal LED
LED Fading mit NodeMCU v 1.0
