+# Keypad and Encoder demo
+
+## Overview
+
+LVGL allows you to control the widgets with keypad and/or encoder without touchpad.
+This demo shows how to handle buttons, drop-down lists, rollers, sliders, switches and text inputs without touchpad.
+Learn more about the touchpad-less usage of LVGL [here](https://docs.lvgl.io/master/overview/indev.html#keypad-and-encoder).
+
+![Keypad and encoder navigation in LVGL embedded GUI library](screenshot1.gif)
+
+## Run the demo
+- In `lv_conf.h` or equivalent places set `LV_USE_DEMO_KEYPAD_AND_ENCODER 1`
+- After `lv_init()` and initializing the drivers call `lv_demo_keypad_encoder()`
