1. 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.

2. What does an I2C module do?

The I2C Bus allows two devices to communicate with each other in a stable, high-speed, bidirectional manner while using the fewest I/O pins. Because the I2C Bus communicates over two lines, Serial Data Line (SDA) and Serial Clock Line (SCL), the protocol used by I2C is also known as a "bidirectional" protocol.

3. 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.

4. What is the I2C protocol for LCD?

The I2C protocol for LCDs uses two wires such as SDA for data and SCL for the clock. It begins with a start condition, followed by addressing, and data transmission, and ends with a stop condition. The LCD controller determines specific commands and data formats.

5. How does the adapter enhance project efficiency?

The I2C communication protocol of the adapter allows control of up to three LCD displays on a single I2C bus, simplifying multi-display projects.
