Maybe this should be added as a comment in the "Manipulate hardware like a arduino" example on https://github.com/nodemcu/nodemcu-firmware

Like the example is currently written it makes one think that one can read the state of the output pin which was set in the preceding line.

In my opinion a read() should not alter the state of the gpio.
Here is a patch for that: https://github.com/jrahlf/nodemcu-firmw ... 3c3a58b7b7

I tested it and it works fine.
