we would want to use a resistor to pull GPIO0 high. 5 That will cause the bootloader inside the ESP8266 to read data from the EEPROM chip into the ESP8266’s IRAM and boot our program.

This is the ESP8266 ... is to use the Arduino compatible mode. This involves loading custom firmware that turns the chip into a mid-range Arduino board, which makes for much easier programming.

In this quick project we’ll show how to use an Adafruit ESP8266 Feather HUZZAH to control NeoPixels or a relay. For this example during a session of Sunday night hacking an Adafruit ESP8266 ...
