The LCD displays each character through a matrix grid of 5×8 pixels. If you happen to have an LCD without an I2C interface incorporated into the design, these can be easily acquired separately.
An I2C LCD advantage is that wiring is straightforward, requiring only two data pins to control the LCD.Ī standard LCD requires over ten connections, which can be a problem if your Arduino does not have many GPIO pins available. The module features a controller chip handling I2C communications and an adjustable potentiometer for changing the intensity of the LED backlight. LCDs incorporate a small add-on circuit (backpack) mounted on the back of the LCD module. The character LCD is ideal for displaying text and numbers and special characters.
We offer both a 2 x 16 LCD along with the larger 4 x 20 LCD. Using an I2C interface, only two connections for an LCD character display are possible with stunning professional results. Adding an external display would typically require several of the limited I/O pins. The ability to interface to external devices readily is very enticing, although the Arduino has a limited number of input/output options. The Arduino family of devices is features rich and offers many capabilities.

I just tried VSCode, because the Arduino IDE keeps creating folders everywhere in my computer and storing libs in all these folders, just to accuse duplicated libs when trying to compile the code. If I uninstall and reinstall PlatformIO (I already did like 5 times), create a new project (I already create some 10 or 15 on my trials), also doesn’t work.Īnd of course, I looked for it in several different forums, some people has the same problem and couldn’t solve it. Wrote on the first lines of my main code, inside the Project’s folder:Īnd that´s all! NOTHING can clean these errors.Added 2 libs to the project: AutoConnect and HttpClient.Setup my board, folders etc successfully.
