ESP8266 Community Forum

- Sat Sep 05, 2015 9:55 am #27869 I tried to run the arduino fade example, with led as BUILD_IN_LED , but the LED always stays on at full brightness. The led is always at its full brightness even on analogWrite(BUILD_IN_LED,0).

Why does this happen?

Can you post the type of ESP (8266-01, 8266-12e are just two of the common ones), any development board and the code you are using. There are many combinations and variables, any of which could be affecting your outcome.
