Initiate the Wire library and join the I2C bus as a master or slave. This should normally be called only once. Syntax 语法 Wire.begin(address) Parameters 参数 address: the 7-bit slave address (optional); if not specified, join the bus as a master. Returns 返回 None Wire.requestFrom()...
There are both 7- and 8-bit versions of I2C addresses. 7 bits identify the device, and the eighth bit determines if it's being written to or read from. The Wire library uses 7 bit addresses throughout. If you have a datasheet or sample code that uses 8 bit address, you'll want t...
Once you’re comfortable installing libraries and looking up how to use their built-in functions, through the included examples and the library’s documentation, the Arduino world really is your oyster. Moving beyond the basic inputs and outputs we coveredin previous episodes, libraries let...

ASoftwareSerial libraryallows serial communication on any of the Uno's digital pins. The ATmega328 also supports I2C (TWI) and SPI communication. The Arduino Software (IDE) includes a Wire library to simplify use of the I2C bus; see thedocumentationfor details. For SPI communication, use the...
The Arduino CLIis a command-line tool for compiling and uploading sketches. You can also use it in place of the Library and Boards Manager. See theArduino CLI GitHub repo. There is an online editing environment called Arduino Create.In order to use this you will need to create an account...
