How to connect Arduino to an LCD with out Potentiometer tutorial

video was much too fast

Thank you it was very useful

music is very distracting

Share circuit diagram and code

How many k resisor u used?

Code ?

There is a mistake in circuit diagram @ in R/W

i cant see anything 144p

First of all, if you're recording something pretty small and precise, you should do it without using a toster instead of a phone.
Your wiring diagram displayed later is incorrect and not the same as the wiring you did in the first part. For everyone that might need this video, here is the wiring:
GND(VDD), RW, BLK --> GND; VDD, BLA[via 2kOhm resistor] --> 5V; V0 --> 6; RS --> 12; E --> 11; D4 to D7 --> 2 to 5, respectively.
Also, your code does not work very well on all displays. For this wiring, a new line is required before lcd.begin() and it's "analogWrite(6, Con); ".Con is a value between 0 and 255, for me the best value was 125, you can experiment and set the right value for you.
