Lcd Backlight Arduino

This tutorial demonstrates how to control the backlight of a 16x2 LCD display using an Arduino Uno and a button. The provided script allows you to toggle the LCD backlight on and off with a button press, offering a simple yet practical application of Arduino's capabilities with the LiquidCrystal library.

Is it possible to turn onoff the backlight of a standard LCD 16x2, this without integrated buttons amp LiquidCrystal.h ? led.nodisplay amp led.clear only affect the text, and the backlight remains on. The LiquidCrystal library that comes with the Arduino IDE deals only with the HD44780U type controller and it's 14-pin interface on your LCD

How to dim the backlight on an 20x4 LCD Display with the i2c connected to an Arduino uno? I use the LiquidCrystal_I2C.h library and I can turn on and of the light with lcd.backlight and lcd.noBacklight But I don't want to turn off completely the backlight I want to dim it.

Arduino LCD Backlight Fix As it stands many Arduino LCD Shields like this have a rather unfortunate design that prevents Dimming of the backlight. In most applications dimming is not required but if you have constructed a Star tracker and the backlight is at full brightness
