Thank you for your answer! I have two more questions: Wouldn't it work to use the voltage regulator as described in youtube.com/watch?v=XdGFzLANsd4? Is it possible to output 3.3V using an analog pin (marked with ~)? The voltage regulator I was thinking to use is: kjell.com/sortiment/el/elektronik/arduino/moduler/….

He appears (for some strange reason) to be using a separate regulator to supply power to the ESP8266 - ignoring the fact that the Arduino has a 3.3V pin which does just that. He also connects Tx/Rx without any level shifting which is wrong. In particular, sending to the ESP8266 should be via a level shifter, or at least a voltage divider.

add language identifier to highlight code
```python
def function(foo):
print(foo)
```
put returns between paragraphs
for linebreak add 2 spaces at end
_italic_ or **bold**
indent code by 4 spaces
