If you wish to run the backlight through the Arduino, you can do so. Using one of the digital pins on your board will make controlling the backlight much easier. The pin can be rotated high or low to turn on or off the backlight. My impression is that this device uses quite a few pins and tends to consume a lot of power. My first choice would be a small OLED display connected to an I2C port. Only 2 pins are needed aside from power and gnu, plus this is extremely low power, and despite its size, you can read it as easily as a 20x4 screen.
A website from Qin Gen Electronics, not Rio Rand, is in fact the manufacturer's. Visit the website. The Qc- Please visit www.com. a better way to search for hd44780 would be to search for it because it is the control chip in almost all character matrix LCDs. Web contains a great deal of information.
My steps were as follows The header on the module is soldered as follows One x40 pin 2. Five pieces one x40 pin 2. 53 mm Angle Single Row Pin Header Strip (just break off the pins you need to make the connector. I then connected a cable strip to Alternatively, you could use the Phantom YoYo 40P dupont cable 200mm male to female, or something like Jumper Cable 2 for RioRand 3 x 40P 20cm Dupont Wire. The thematic column for 1P is 54. --- SEP-01- 1 P I am male/female A woman/a woman The male gender. All of these products are available I love the way it works. The following warning should be heeded If you cannot use the pins that are already attached to the wires and have to strip insulation and reinstall the pins, the wires in the cable strip are very fine and difficult to work with The soldering process.

The white on blue 20x4 LCD module features 2 lines of text. With the help of a header, I connected the display to a breadboard and connected it to an Arduino Uno, and it went on right away. Those who have described the contrast adjustment have given detailed explanations of how it works. Despite the fact that I am not an expert on these things, the connections to the display seem to be the same as those of the numerous displays there I found some examples of line endings. This display may not be working for you, so you should check out these sites Try it out and see how it works by downloading samples of code and wiring instructions. Observations

I found programming to be very easy. The ribbon cables from Arduino to the LCD are straight across when the ribbon cables are aligned properly. This is how the cables I used looked. - br -.
The LCD is good and does what it is supposed to. The soldering went smoothly after it was shipped and I have attached a couple of pictures. Besides the follow way, some people have suggested other ways of wiring it. The follow way works nicely and is relatively easy. Also, below is some code for testing. Item

The price was good for a 20 x 4. It would have been nice if the kit came with mounting hardware (male and female pin headers) and a potentiometer. It can easily display useless data and does not refresh very fast, so if you are coding a stop watch with tens of a second you will be in trouble. I have soldered female headers on the chip so I can use it with a breadboard quickly. I would like to remind you that On the model I received, the screen displays correctly when the pins are pointing upwards. I don't know why, but the product photo shows the opposite of what I expected.
A friend gave me one of these to put in There is a web-based Retro IC tester (you can find it on Google). I tried it out immediately. In the unit which I received, the series resistor was a 0 ohm - it worked just fine. In certain units, the position where the resistor is located has an actual resistor. As it lacks an interface chip for SPI, it cannot communicate with it. My need for it was not there. It required that I solder on the pin header to connect it to the motherboard of my project. Nevertheless, it is a good thing, since this unit is more flexible with regards to its configuration. It's a good buy for the money in the end.
