Wire — Library Arduino [better]

if (Wire.available() >= 2) int msb = Wire.read(); int lsb = Wire.read(); int data = (msb << 8) delay(100);

For 90% of I2C projects, Wire is all you need. For advanced needs (multi-master, >32-byte transactions, non-blocking), consider platform-specific I2C libraries. wire library arduino

// Request 2 bytes from slave Wire.requestFrom(0x68, 2); if (Wire

void loop() Wire.requestFrom(0x08, 1); if (Wire.available()) int received = Wire.read(); Serial.println(received); if (Wire.available() &gt

void loop()

❌ Limited buffer size, blocking, minimal error recovery.
