I'm not having luck using the Arduino IDE to blink and LED on the new NodeMCU v2 (4Meg) version I just got in the mail. No external leds are used. I just want to blink the one on the NodeMCU. In the IDE I select Tools/Board/NodeMCU (ESP8266 ESP-12 Module), the correct port and Upload the Example/Basic/Blink sketch but nothing. I've changed the I/O pin to 0 but no LEDs are blinking. Is I/O pin 0 not the correct one?
