Customer:
Where can I find the Arduino library for the I2C LCD driver adapter? The product page mentions an Arduino library is required, but I need to know where to get it.
Na stranici I2C LCD drivera (koju možete vidjeti na ovom linku) naveden je “Arduino library” koji je potreban za korištenje adaptera. Zanima me gdje mogu naći taj library?

Soldered Support:
You can use the library from GitHub - SolderedElectronics/Soldered-16x2-LCD-Arduino-Library · GitHub, but it is currently designed only for 16x2 LCD displays. Libraries for other LCD sizes will be available in the future.
možete koristiti library s ovog link-a GitHub - SolderedElectronics/Soldered-16x2-LCD-Arduino-Library · GitHub, ali on je trenutno namijenjen samo za LCD 16x2. U budućnosti biti će dostupni library i za ostale LCD-ove.
Customer:
I followed the installation instructions from the blog post to install the library. I placed the src/ directory from the zip file and imported it into Arduino IDE on Windows as explained. However, even with the ‘Hello world’ code from GitHub, Arduino reports that the LCD control commands cannot be found.
Pratio sam link s vaše stranice (koji možete vidjeti ovdje https://e-radionica.com/hr/blog/2015/08/19/arduino-library/) da instaliram navedeni library. U zip file sam stavio src/ direktorij te ga importo u Arduino IDE na Windowsu kako je objašnjeno na toj stranici. No, čak i s ‘Hello world’ kodom s Github-a Arduino javlja da se naredbe za kontrolu LCD-om ne mogu naći.
Soldered Support:
It’s possible the library was not installed correctly, as I tested the Hello world example and it works.
Library installation procedure:
When you open GitHub - SolderedElectronics/Soldered-16x2-LCD-Arduino-Library · GitHub, go to Code → Download ZIP. Extract the downloaded file. Copy the folder that is inside the extracted archive and paste it into the Arduino libraries folder. In my case, this folder is located at C:\Users[user]\Documents\Arduino\libraries. Now in Arduino IDE you can select the desired example.
postoji mogućnost da niste dobro instalirali potrebni library, jer sam testirao Hello world primjer te radi.
Postupak instaliranja library-a:
Kada otvorite ovaj link: GitHub - SolderedElectronics/Soldered-16x2-LCD-Arduino-Library · GitHub, idete na Code → Download ZIP Zatim tu skinutu datoteku morate extract-at Mapa koja se nalazi unutar te extract-ane mape, kopirate te zalijepite u Arduino library. U mom slučaju navedena mapa se nalazi u C:\Users[user]\Documents\Arduino\libraries Sada u Arduino IDE možete odabrati željeni primjer.
U prilogu Vam šaljem još video testiranja Vašeg koda, te sliku zalemljenog driver-a na LCD-u.

I successfully installed the library following your instructions. The pins on the adapter are soldered and connected to SDA, SCL, 5V, and GND on an Arduino Uno. The adapter came pre-soldered with the LCD. However, the LCD is not displaying anything—it just flickers as it should with the Hello World example code.
Hvala na informaciji. Uspio sam instalirati library po vašim uputama. Zalemljene pinove na adapteru možete vidjeti na slici u prilogu. Spojeni su na SDA, SCL, 5V i GND na Arduino Unu. Adapter je kupljen s LCD-om (već je zalemljen). No, LCD ne ispisuje ništa, samo flickera kako bi i trebo (koristim Hello World kod iz primjera).

The LCD adapter has a potentiometer that allows you to adjust the contrast of the LCD display. Please try adjusting it.
na LCD adapteru se nalazi potenciometar pomoću kojega je moguće namjestiti kontrast LCD-a, pa Vas molim da to probate.
