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.

I prefer the additional 8 ports on this module over the PCF8574 modules, which are also available on Amazon. Customers should be informed that the Red circuit board PCF8574 modules on Amazon (the ones without a second connector for linking modules together) have a built-in 1K pullup resistor on the interrupt pin, while the Blue circuit boards (which have a second connector for linking) do not. (https://www.amazon.com/gp/product/B01ICN5JB6/ref=ppx_od_dt_b_asin_title_s00?ie=UTF8&psc=1) I've used the Red PCF8574 modules.) and they operate Raspberry Pi well. However, I was unable to successfully implement interrupts for these PCF8575 modules without an extra 1K pullup resistor to VCC on the INT pin. Because of the INT...
The poor contrast of TFT technology has always been its fundamental flaw. By using in-plane switching (IPS), which produces extremely high contrast, the color is introduced into the same plane as the backlight (the word "backlight" would be incorrect in this instance because the light plane is no longer behind the color plane). This display has the same appearance as an OLED panel but is less expensive and has less color fading over time. There is a lot of driver software available; in the image, I'm using the circuitpython chip sample. So far, the driver chip has only been used to drive the SPI at 24 Mhz, which it does without issue. This 2-inch display's strong contrast makes it just as readable as larger ones. The decision...
For some outdoor projects, I've been utilizing SIM7600G-H pi hats for RPi, however these may get pricey. For embedded projects, this lilygo board is more cost-effective and superior. I wish the Arduino MKR1500 had an ATECC608b chip as well. However, this is readily added, and the board is still less expensive than an Arduino. It also has wifi and Bluetooth, a battery holder, solar charging, and an overcharge safeguard for 18650 batteries. I had no trouble connecting to the Project Fi network. It took a few minutes to connect, and I just needed to reset the gadget once. This could be the result of an incorrect antenna connection the first time. The 18650 protected battery is not very well fitted. I'll attempt this later without the protected 18650 battery because this board includes overcharge protection. A few drawbacks: The side switch is of extremely low quality. The delicate element of the PCB is the ESP32's exposed antenna.
