I wanted to have a menu in an upcoming project and use a rotary encoder with a centre push button as my input hardware. This is really similar to the LCD controllers for RAMPS and Arduino MEGA 3D printers.

Nov 2, 2020 · In this video I show you my improved menu system for Arduino/STM32. The code works on both microcontroller thanks to the STM32duino. By using a rotary encoder and a button, we can navigate on the display (20x4 LCD) and select a menu, then modify the value of a variable based on the selected menu.

If you power the Arduino module and by pressing the buttons you will be able to change the menu selection on the LCD and change the values using a rotary encoder. If you press the button on the rotary encoder the values will be stored to Arduino EEPROM and loaded on the start.

Aug 24, 2019 · In this example, I’m using a rotary encoder with a 20×4 LCD display in order to control a menu. This is a simple example that also uses the rotary library from Ben Buxton and modified by Phill Fisk, who included the push button feature.

Nov 29, 2020 · It is based on the Frank de Brabander's library for text I2C displays. I added some functions for formatted output, input and value selection, definition the menu. You can find the source code and examples on github: GitHub - VladimirTsibrov/LiquidCrystal_I2C_Menu: Arduino library for LiquidCrystal displays that use the I2C bus.

Arduino menu library for LCD displays 16x2 and 20x4. Features: multiple menu levels; control by 4 buttons keypads (4xDI or 1xAI) or by rotary encoder (4xDI) menu texts stored in program memory; displays actual state of inputs or variable values; direct control of outputs

Aug 20, 2024 · With any luck, this Instructable will empower you to experiment with a simple menu system and pair it with a rotary encoder to elevate the professionalism of your upcoming project! The reason why menus and rotary encoders require coding.

In our last tutorial, we examined how to create a menu for your Arduino project on a Nokia 5110 LCD, with push buttons to navigate through it. In today’s tutorial, we will build a modified version of it which will make use a rotary encoder (in place of the push buttons) for menu navigation.

Mar 14, 2018 · Now, it is controlling 3 variable attached to analog outputs. wiring is really simple. SDA, SCL, two pins for encoder, one pin for built in button... if (digitalRead(encoder0PinA) == HIGH) { . if (digitalRead(encoder0PinB) == LOW && encoder0Pos > 0) { . encoder0Pos = encoder0Pos - 1; . dir = 0; . else { . encoder0Pos = encoder0Pos + 1; . dir = 1; .

Apr 5, 2022 · In this detailed tutorial learn how to interface a Rotary encoder with Arduino and display the encoded directional values on 16X2 LCD display when rotated in clockwise and anti clockwise directions. And also learn about Rotary encoder and how it …
