Questions & Answers
This LCD display should be treated the same as any other 16x2 In short, this is the same except you have a common ground and, as I recall (it's been a while), 3 anode connections that let you choose between LED colors. (For back lighting, 3 color LEDs are used). To create a variety of colors, you can adjust the brightness by adjusting the duty cycle or the resistance. Display aspect of the LCD is similar to any other 16x2 LCD. It should work if you type hello world. Please double check that your connections are correct and your data buses are in the correct Hopefully this will be helpful to you.
A header pin is not included in this display Installation completed
There is no LCD module which works with anything but
A contrast pot and headers are not included with the LCD. It needed headers to work, so I soldered them on. The situation is not a problem. The following is an excerpt from Phil Warner's blog

The order was for 3 and I It was an error on my part. BE CAREFUL to understand what these are NOT. This product might be good for some functions, but be smart and know what you need. RGB displays with WHITE letters or colored letters on a white background are not the displays at hand. As for the characters themselves, they are all black. At a distance from the display, BLACK letters are difficult to read. When displays have WHITE or COLOR display letters, the letters can be clearly seen. When viewing these displays close up, they are best suited to close viewing. Both types of my blood are in my body. The colors on these will NEVER change from black to white or white to black, regardless of what color background you select. I bought these just thinking they had cooler WHITE lettering on a dark background. You would be surprised how many LCD buyers don't recognise this important distinction when buying their displays. We wish you all the best. I should mention that the PCB is nice and high quality.
The first thing I want to mention is Goods arrived ahead of my estimate, were well packed, and were exactly as pictured online. Having never used displays before, I'm glad I chose this one as my first choice. You can read the Lady Ada tutorials on LCD displays if you have access to My first step was to follow tutorials 11 and 12 followed by the general LCD tutorial. The tutorials told me everything I needed to know to start. The caveat is There are pins on this display that need to be connected to a header. You should order both at the same time. Since they are required for wiring the display to the breadboard, they do not come with it. Tech Wizards was where I bought mine. I will not repeat Simon Monk's Lady Ada tutorials on what pins on the display need to be connected to what on your Arduino, so I will not go into it If you follow the tutorials, you can load any sample sketch under LiquidCrystal in the IDE, and don't forget to replace LiquidCrystal lcd(12, 11, 5, 4, 3, 2) with your own. If you use pins, you should use whatever pins are actually used. example, I have the LiquidCrystal 12 lcd line (6, 7, 8, 9, 10, 11) Regardless of the default colors coming out of this thing, reading some other reviews can help you get more out of it. However, some of the other ratings give you hints on gettng more out of it than its default colors, just by turning up or down pins 16-23. On the LCD, there is 18 on the screen. Hope you have a successful run!.
Despite the fact that it costs a few dollars more, I would be happy to purchase a brighter version of the game.
Considering this is an HD44780 compatible chip, I would suggest looking very closely at the first 6 pins, the 10k pots, and how the wires are connected if you are experiencing any problems. arduino compiler should give you all the information you need to get this up and running within 5 minutes of clicking the link on the supplied sketches. I love how affordable the price is, I love how there are 3 options for colors. The LCDs add a lot to any project that has an LCD. I hope they stay created for a long time. Additionally, you have color choices and a number of feedback options. In case you want a static color, you can always break out the 3 colors with variable resistors and get a custom color, but the 3 basic colors give you a wide range of options without messing around too much with your Arduino or taking up 3 PWM channels.
Any project that requires a 16x2 display will benefit from this product. This contrast is of excellent quality, and can be controlled by any variable DC voltage source (e. g. You may also use a DAC, potentiometer, It is possible to set a RGB LED backlight to change colors, particularly for alarms, so that the backlight has a nice colored effect.
There are two rows of 16x2 LCDs on this If you need to test the LCD, you can use the LCD test program from the Arduino IDE. To change the background color beyond the basics, you will need more pins on your Arduino board. That is to say that you can use the left 4 pins to make red, green, blue, purple, or white by just connecting power and ground (and these will not The process can be a little more challenging if you require something fancier. As a result, I was able to solve the problem by loading the LCD program in the Arduino IDE that comes with the board and connecting the pins as instructed (6 data pins,.
This is a great tool. It was no problem for the Arduino Uno. I was sold on the RGB because of its versatility. Since I will be using it in a photography darkroom, the feature of being able to change the display color will be nice. It was an excellent price and shipping was fast. If I could buy again, I would. It is likely I will buy a half dozen for various projects I am working on.
I found this to be effective. It is highly recommended that you use this with the Adafruit I2C/SPI backpack if you are using it with an Arduino. These are great for me and I plan on buying more Adding them to any project really gives it a unique look.
