Are I2C and NodeMCU compatible?
NodeMCU has GPIO pin support for I2C capabilities. We are unable to use all of the E P-12E's GPIO for I2C functionality due to internal circuitry. o, before using any GPIO for an I2C application, perform the following.
Is hardware I2C present in the E P8266?
The I²C (I2C, IIC) is a serial 2-wire bus used for multiple device communication. Although MBUs have some additions to the I2C protocol, neither a TWI nor an MBU is known. The E P8266 chip uses an OFTware I/C driver instead of a hardware I/C module.
How can a 16x2 LCD be connected to a NodeMCU?
Connect the 16x2 LCD to the pin of the I2C module. Attach the NodeMCU's GND pin to the GND pin of the I2C module and its VIN, or 3.3-volt pin, to the VCC pin of the module. For the NodeMCU Tutorial, connect the digital-2 pin of the NodeMCU to the DA pin of the I2C module.

Which library should I use for an I2C device?
the Library on WireThe Wire library is the standard Arduino I2C library. Although this library is often sufficient, there are instances in which it cannot be used, such as when the I2C pins A4/A5 (or DA/CL) are already in use for other purposes.
I2C liquid cry: what is it?
You can program an Arduino to print your age on an LCD by using the LiquidCry tal_I2C library, which creates an I2C backpack. With just a few pins, you can communicate with various devices thanks to the I2C communication standard.

How is an I2C LCD used?
According to the circuit design below, an I2C LCD can be directly linked to an Arduino by connecting DA pins to DA pins and CL pins to CL pins. An additional library must be installed for I2C LCDs. The next step is using the following code to link the LCD to the device's address. The specifics of each are discussed below.
