128 gadgetsDevice Addressing for I2CSince a 7-bit value can range from 0 to 127, this indicates that there can be up to 128 devices on the I2C bus. We continue to send 8 bits whenever we transmit a 7-bit address. The additional information is intended to let the slave know whether the master is reading from it or writing to it.

Before connecting the LCD screen to your Arduino board, we advise soldering a pin header strip to the connector's 14 (or 16) pin count, as seen in the figure above. Connect the following pins to your board in order to connect your LCD screen: RS pin on LCD to digital pin 12. Pin to digital pin 11 enabled.

An advantage of using I2CFlexible, with the ability to support communication on multiple channels. Use only two bidirectional wires to enable communication between numerous devices. It is flexible and can adjust to the requirements of various devices. support a variety of media.

The I2C interfaceIt only makes use of two lines, one of which serves as a clock for synchronization and the other as a data line. This data line can travel both ways. In other words, if there are two data lines in SPI-one incoming and one outgoing-there is just one data line in an I2C interface.

connections between integrated circuitsInter-Integrated Circuit (I2C) connections are used!

Because I2C just requires two wires and allows several devices to share those lines, it is highly popular and a fantastic way to connect a large number of sensors, drivers, and expanders without using up all the microcontroller pins.

I2C Communication Protocol Operation:SDA and SCL, two bidirectional open-drain lines, are the only ones used for data transfer. These two lines have been raised. Data is transferred over this pin through serial data (SDA). The clock signal is carried by the serial clock (SCL).

How to Determine the I2C AddressYour LCD's I2C address is 0x27 if it uses a PCF8574 chip from Texas Instruments; 0x3F if it uses a PCF8574 chip from NXP Semiconductors.

The address in question is 0x27 (dicovered using the I2C canner Code). 16 in the first column and 2 in the first row. We can now refer to the digital playback device as an LCD. With the Arduino Uno, you can utilize numerous I2C LCD displays.

It's very easy; all you have to do is solder the I2C to the LCD's ports and plug it in. After that, join the SCL pin to the Arduino's A4 pin and the SDA pin to its A5 pin.

Since the I2C 16x2 Arduino LCD Screen uses an I2C communication link, it simply requires the microcontroller's VCC, GND, SDA, and SCL pins to power the LCD display. Since the Gadgeteer wiring system is no longer manufactured, you probably won't need the "Gadgeteer" cable that comes with the display.
