So I was trying the example used here: https://www.arduino.cc/en/Tutorial/HelloWorld
The display I am using is the 1602 display with an Arduino UNO.
See photo below attached for my connections.
The display lights up, but no texts or boxes are showing on the screen. Even when I turn the potentiometer, nothing shows up or no changes at all. Help me :(
PS. I also believe it's not because of my soldering because I have tried soldering before on other components and they work just fine.
