Product Introduction
The Arduino UNO R3 is a classic classic entry-level open-source microcontroller development board in the Arduino series, using the ATmega328P microcontroller chip. Arduino supports the use of simple C/C++ languages and can be programmed and used through the Arduino IDE.
Product Serial Port Diagram
The serial port functions of Arduino UNO R3 can be divided according to the pin order: among the analog pins, A4 (SDA) and A5 (SCL) are dedicated to I2C communication, which need to be used with the Wire.h library to connect sensors and other devices, while A0-A3 are ordinary analog inputs; among the digital pins, D0 (RX) and D1 (TX) are hardware serial ports (UART), which are default used for USB communication and Serial debugging, D2-D9 can be used as general-purpose IO or simulate serial ports through the SoftwareSerial library, and D10 (SS), D11 (MOSI), D12 (MISO) and D13 (SCK) form an SPI interface for high-speed data transmission, which needs to be used with the SPI.h library. The hardware serial port and I2C are fixed functions, and the remaining digital pins can be flexibly configured for use.
