16x2 LCD (Blue) with I2C Interface

This is a great LCD module for different types of Arduino projects. If you want to display your results and see the output, the 16x2 LCD Display is the perfect component for DIY Arduino projects. The values shown on the 16x2 LCD can be either a simple text or numerical values read by the sensors, such as temperature or pressure. This 16x2 LCD Display with Blue Backlight is extremely simple to connect to an Arduino or other microcontrollers.

The I2C interface module modules are currently supplied with a default I2C address of either 0x27 or 0x3F. To determine which version you have check the black I2C adaptor board on the underside of the module. If there a 3 sets of pads labelled A0, A1, & A2 then the default address will be 0x3F. If there are no pads the default address will be 0x27.

1. What is a 16x2 LCD display?

  • The 16x2 LCD Display is a simple and cost-effective LCD display with 16 character by 2 line with very clear and high contrast. This 16x2 LCD is extremely simple to connect to an Arduino or other microcontrollers. The values displayed on the 16x2 LCD can be simple text or numerical values read by the sensors, such as temperature or pressure, or even the number of cycles performed by the Arduino.

2. How many data lines are needed for 16x2 interface?

  • The LCD 16x2 is a 16-pin device with eight data pins (D0-D7) and three control pins (RS, RW, EN). The remaining 5 pins are for the LCD's power supply and backlight. The control pins allow us to set the LCD to command or data mode. They also assist in configuring read mode or write mode, as well as when to read or write.

3. What is I2C interface module?

  • I2C is a single-ended, synchronous, multi-slave, multi-master packet switched serial bus. In other words, multiple chips can be connected to the same bus. I2C employs only two bidirectional open collector or open drain lines, Serial Data Line (SDA) and Serial Clock Line (SCL), which are connected with resistors.

4. How to connect LCD with I2C?

  • Simply connect the I2C module to the LCD in parallel and the I2C module's four pins to the Arduino. The I2C module has four output pins: VCC, GND, SDA, and SCL, and it receives 5V from the Arduino via VCC and GND. SDA is the data pin and SCL is the clock pin of the I2C module.
