The principle of the LCD1602 liquid crystal display is to use the physical characteristics of the liquid crystal to control the display area by voltage, that is, the graphic can be displayed.

I2C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL),pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted. It can be operated as long as it supports the I2C development board.

Features: Easy to use; Less I/O ports are occupied; Support IIC Protocol; The I2C LCD1602 library is easy to get; With a potentiometer used to adjust backlight and contrast; Blue backlight; Power supply: 5v; I2C address is: 0x27.

How to connect it to Raspberry Pi and Ar-duino Compatibility Used for connecting Ar-duino and Raspberry pi and it can be used to display real time clock, temperature, humidity etc.

You can display the digital information or English sentense on the LCD screen by using Arduino, Raspberry Pi or other MCU which supports i2c protocol.

※Price Increase NotificationThe TFT glass cell makers such as Tianma,Hanstar,BOE,Innolux has reduced or stopped the production of small and medium-sized tft glass cell from August-2020 due to the low profit and focus on the size of LCD TV,Tablet PC and Smart Phone .It results the glass cell price in the market is extremely high,and the same situation happens in IC industry.We deeply regret that rapidly rising costs for glass cell and controller IC necessitate our raising the price of tft display.We have made every attempt to avoid the increase, we could accept no profit from the beginning,but the price is going up frequently ,we"re now losing a lot of money. We have no choice if we want to survive. There is no certain answer for when the price would go back to the normal.We guess it will take at least 6 months until these glass cell and semiconductor manufacturing companies recover the production schedule.

ER-OLEDM032-1B is the 256x64 blue pixels OLED display with adaptor board that simplifies your design,diagonal is only 3.2 inch.The controller ic SSD1322, communicates via 6800/8080 8-bit parallel and 3-wire/4-wire serial interface. Because the display makes its own light, no backlight is required. This reduces the power required to run the OLED and is why the display has such high contrast,extremely wide viewing angle and extremely operating temperature.Please refer to below interfacing document for how to switch to different interface. The default interface is 8-bit 8080 parallel.

It"s easily controlled by MCU such as 8051,PIC,AVR,ARDUINO,ARM and Raspberry Pi.It can be used in any embedded systems,industrial device,security,medical and hand-held device.

Of course, we wouldn"t just leave you with a datasheet and a "good luck!" We prepared the interfacing documents,libraries and examples for arduino due,mega 2560,uno,nano and for raspberry pi or raspberry pi zero.For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and Development Kit at the bottom of this page.

The platforms mentioned above as supported is/are an indication of the module"s software or theoritical compatibility. We only provide software library or code examples for Arduino platform in most cases. It is not possible to provide software library / demo code for all possible MCU platforms. Hence, users have to write their own software library.

Step 4. Please follow below picture to select example HelloWorld and upload the arduino. If you do not know how to upload the code, please check how to upload code.

Step 1. Using a Grove cable connect Grove - LCD RGB Backlight to Seeeduino"s I2C port. If you are using Arduino, please take advantage of a Base Shield.

As we all know, though LCD and some other displays greatly enrich the man-machine interaction, they share a common weakness. When they are connected to a controller, multiple IOs will be occupied of the controller which has no so many outer ports. Also it restricts other functions of the controller. Therefore, LCD1602 with an I2C bus is developed to solve the problem.

I2C bus is a type of serial bus invented by PHLIPS. It is a high performance serial bus which has bus ruling and high or low speed device synchronization function required by multiple-host system. The blue potentiometer on the I2C LCD1602 (see the figure below) is used to adjust the backlight for better display. I²C uses only two bidirectional open-drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL), pulled up with resistors. Typical voltages used are +5 V or +3.3 V although systems with other voltages are permitted.

Step 3:Since in some code, the libraries needed are not included in Arduino, so you need to add them before compiling. Unzip the downloaded file. Copy the folders under the Library folder to the libraries folder in Arduino (if you cannot find the path in Arduino, open Arduino IDE, click File ->Preferences, and you can see the path in the Browse box, as shown in the following diagram). Compile the program.

The principle of the LCD1602 liquid crystal display is to use the physical characteristics of the liquid crystal to control the display area by voltage,

Before we get into the programming, we need to make sure the I2C module is enabled on the Pi and install a couple tools that will make it easier to use I2C.

By inserting the variable from your sensor into the mylcd.lcd_display_string() function (line 22 in the code above) you can print the sensor data just like any other text string.

This is an I2C 1602 LCD module, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already have I2C devices in your project, this LCD module actually costs no more resources at all. It is fantastic for Arduino based project.

Everyone love the 1602 character LCD, is cheap and works out of box! But the need for 6 to 10 GPIOs is the pain :) It takes most of GPIO of Arduino and other microcontroller. Now with this I2C or Two wires interface LCD, you will save a lot of GPIO for your sensor and motor control.

LCD shield after connected with a certain quantity of sensors or SD card. However, with this I2C interface LCD module, you will be able to realize data display via only 2 wires. If you already has I2C devices in your project, you can still program this LCD with the correct I2C address. It is fantastic for Arduino based project.
