I have 5 Menu such as 1.AAA 2.BBB 3.CCC 4.DDD 5.EEE I want to select menu from rotate and single click rotary encoder and Show Display on LCD 16x2 I2C But i don't know how to write code with Node MCU ESP8266 Please help me!!!
What have you done so far? Have you connected the LCD? Can you display text on the LCD? Can you read when the encoder button is pressed? Can you read the encoder? Which LCD? Which encoder?
Please read the "how to use the forum-please read" stickies. You will see what we need to know in order to help you and how to format and post your code.
I connect all already. but I don't know how to write a code with NodeMCU arduino.
The code for a NodeMCU is, essentially, the same as for any Arduino if you are using the Arduino core. This tutorial shows how to get and set up the Arduino core. There is example code with the liquid crystal library to help you get that going. This page has information on using rotary encoders.
We will not write the code for you, you must make an effort. When you have trouble, post your code with a description of what the code does and how that differs from what you want the code to do.
And, please, try to answer questions that are asked (Which LCD? Which encoder?).
I show result on LCD Display and Select Menu from Rotary Encoder.
I know what you want to do. What I don't know is what you expect us to do. If you want us to write the code for you, I suggest that you request the moderator to move your post the the Gigs and Collaborations page. Expect to pay someone to write your code and also expect to provide the necessary information. If you want help to write the code yourself, you must respond to questions with more than repeating "I want ...".
