Hey guys i want to use Arduino as a usb to tll converter to upload code to my Nodemcu could you help me with the circuit i would really appreciate it !
Look what a 10 second search found USB to TTL Using an Arduino
Ι have already seen that dumbass...i am refering to the circuit with node mcu but you probably dont know how to read properly
The principles are the same whatever the target board is but due to your attitude you will get no more help from me.
Don't be surprised if someone reports your post to the moderators for being abusive, but I won't be responding to such a report if it occurs and will leave it to others to decide on any action that might be taken
Since a NodeMCU already contains the USB-to-serial (not TTL) converter, this actual question makes no sense for a start. 
So bad in so many ways.

Well, it would not be the OP's first encounter with the moderators!

Whats a 'tll' converter' ?
A TTL converter with a tremor? 
There is a book I can recommend...
How to win friends and influence people. By Dale Carnegie
I was wondering why you chose to cite this - but then I figured it out.
Paul, I would normally be fastidious about quoting etc, but on an iPad, doing anything properly on this forum is an uphill struggle!
It was a sincere suggestion to the OP who seems unable to interact with grown ups!
