Jan 17, 2013 · According to the PDF you posted there are LEDS for backlight. You could connect this to a PWM pin of the Arduino and adjust the back light...

Nov 28, 2020 · There are many different types of LCDs out there and if/how they support backlight control can very substantially. Controlling the backlight depends on the LCD hardware being used and library being used to control it. Some LCD h/w includes support to control the backlight and some don't.

Jul 29, 2012 · This tutorial will show you how to build and use the Adafruit RGB LCD Arduino shield. We have a great library that makes it incredibly easy to use the LCD and the 5 included buttons while only using 2 pins on the Arduino!

Find out how to wire an LCD to an Arduino, and how to use the LiquidCrystal library through a set of useful examples. This article was revised on 2021/11/18 by Karl Söderby. The LiquidCrystal library allows you to control LCD displays that are compatible with the Hitachi HD44780 driver.

Nov 20, 2014 · Today I ordered a 2x16 character LCD with white characters on black background. Now I am wondering if I can change the backlight LED, which I guess is white for the characters, with a RGB LED to change the character color. Did anyone do this before? Is it even possible that way? I've seen RGB negative LCDs from Adafruit and Sparkfun.

Jul 29, 2012 · We now stock a few different RGB backlight LCDs. These LCDs work just like the normal character type, but the backlight has three LEDS (red/green/blue) so you can generate any color you'd like. Very handy when you want to have some ambient information conveyed.

It’s as simple as wiring the upper pin (the one labeled LED) of the I2C board to a PWM pin in the Arduino. Using analogWrite() will vary the LED brightness from 0 (LED off) to 255. Here’s a simple sketch (for a 16 x 2 LCD) to demonstrate this:

Feb 19, 2025 · Interface directly with the RGB backlight pins on an 18-pin RGB LCD Display. This library is compatible with all architectures so you should be able to use it on all the Arduino boards. Was this article helpful?

Nov 21, 2019 · I've just gotten hold of a 7 colour RGB LCD 16x2 which I want to use with I2C and be able to change the colours. However I don't know which I2C backpack would be best or which library to use. I have a PCF8574 I2C module …

Jan 20, 2020 · This Grove 16×2 LCD comes with a full-color backlight. High contrast and ease of use makes it a perfect I2C 16×2 LCD with Arduino and Raspberry Pi. This enables you to set to any color via the simple and concise Grove interface.
