I am following this tutorial http://randomnerdtutorials.com/esp8266-web-server/ as simple webserver to turn on/off led.

I noticed that if I just leave the whole setup, the LED will sometimes flicker and be "half" on. it is like the pins are receiving random signals..

Any ideas? is there something like void setup as output and digitalwrite pin like in Arduino IDE..?

Thanks

i removed the uart serial and the problem seems to have gone away. Apparently, the UART is not providing enough current.
