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 BUILTIN_LED to find the pin with the internal LED
