  2. The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Controller board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices.

    Arduino devices have one or two I2C buses. Each bus has an I2C Central connected to two bidirectional lines, serial data line (SDA) and serial clock (SCL). These two lines are connected to a pair of pins on the hardware. You can connect multiple I2C devices, such as ADCs, LCDs, and sensors, to the I2C pins on the Arduino hardware.

    To use the Arduino’s built-in I2C interface, we will use the Wire library. This library is included with the Arduino IDE, so there’s no need to install it. The Wire library has ready-made I2C functions to make the programming easier for us. To use the functions in the Wire library, we first need to add it to our sketch.
