Inter-Integrated Circuit (I2C) Protocol - Arduino Docs
The Wire library is what Arduino uses to communicate with I2C devices. It is included in all board packages, so you don't need to install it manually in order to use it. To see the full API for the Wire library, visit its documentation page .
Matter Temperature Sensor with the Arduino Nano Matter
Use the following connection diagram for the project: Project wiring diagram. The OLED display and the DHT temperature sensor are powered by the Nano Matter 3.3 V output pin. The OLED display uses I2C for communication and the DHT sensor uses a one-wire digital communication connected to D4. Programming
