Arduino Wire.h Library -

| Function | Purpose | |----------|---------| | Wire.begin() | Join the I2C bus as master or slave. | | Wire.beginTransmission(address) | Start communication with a specific slave. | | Wire.write(data) | Queue bytes to send. | | Wire.endTransmission() | Send the queued data. | | Wire.requestFrom(address, bytes) | Request data from a slave. | | Wire.available() | Check how many bytes have been received. | | Wire.read() | Read a byte from the receive buffer. | | Wire.onReceive(handler) | Define a function called when data is received (slave mode). | | Wire.onRequest(handler) | Define a function called when data is requested (slave mode). |

if(Wire.available() >= 5) ((long)Wire.read() << 8) delay(1000); arduino wire.h library

The story of the Arduino Wire.h library is not just a story about code; it is a story about translation. It is the tale of how a rigid, industrial protocol was tamed into a friendly, two-line command that empowers millions of hobbyists to build complex machines. | Function | Purpose | |----------|---------| | Wire

I2C is a synchronous serial communication protocol that allows multiple devices to communicate with each other over a single bus. It's commonly used in embedded systems, robotics, and IoT applications. I2C uses two wires: | | Wire
