Description

This standard green backlight HD44780 LCD is great for your arduino projects. It supports 16 characters wide and 2 rows in black text on green background. As the pin resources of Arduino microcontrollers is limited, your may be not able to use normal LCD shield after connected with a certain quantity of sensors or SD card. However, the I2C serial interface only take 2 wires to realize data display. If you already has I2C devices in your project, this LCD module actually cost no more resources at all.

You need solder the I2C serial interface module to the 1602 LCD module by yourself.

A: The ’16×2′ in ’16×2 Character LCD’ refers to the size of the display. Specifically, it denotes that the LCD can display up to 16 characters per line, with a maximum of 2 lines. This means you can display a total of 32 characters at any one time on the screen.

A: A 16×2 Character LCD commonly uses a parallel interface with a minimum of 6 pins for proper functioning. These include RS (Register Select), E (Enable), D4, D5, D6, and D7 for data lines when operating in 4-bit mode. Additionally, you need to connect VSS, VDD, and V0 for power and contrast control, and A and K for the backlight. Specific connection diagrams and code will depend on the microcontroller you are using. In many cases, you can simplify the connection by using an I2C adapter module which reduces the number of pins required for interfacing.

A: If your LCD is powered on but not displaying characters, there could be several possible issues. First, check that your connections are correct and secure. Second, verify that your code is properly written and uploaded to the microcontroller. Third, adjust the contrast potentiometer. Too low or too high contrast can cause the characters to be invisible. If all these are fine, you might have a faulty LCD.
