Once that message is received, it can then be viewed in the Arduino Software (IDE) serial monitor window. Arduino 1, the Controller, is programmed to request, and then read, 6 bytes of data sent from the uniquely addressed Peripheral Arduino. The CAN or Controller Area Network protocol was conceived by Robert Bosch (of GmbH) in the 1980s. In serial communication, the data bits are transmitted one at a time in a sequential manner over. Several functions of Arduino's Wire Library are used to accomplish this. Serial Communication Protocols: The Basics Serial Communication.

In this example, two boards are programmed to communicate with one another in a Controller Reader/Peripheral Sender configuration via the I2C synchronous serial protocol. In some situations, it can be helpful to set up two (or more!) Arduino boards to share information with each other. While the above tutorials were written specifically for the Nano Family boards, they can be adopted to any Arduino board.

See the image below to understand how to locate the correct pins on your board.Д¬heck out the following tutorials to get a more detailed step-by-step on how to use I2C on Arduino boards: For example, the pins used for MKR WiFi 1010 are D11, D12, while the pins for UNO are D18, D19. Please note that the I2C bus is attached to different pins depending on the board you are using.

When this information is sent - bit after bit -, the called upon device executes the request and transmits it's data back - if required - to the board over the same line using the clock signal still generated by the Controller on SCL as timing.Д«ecause the I2C protocol allows for each enabled device to have it's own unique address, and as both controller and peripheral devices to take turns communicating over a single line, it is possible for your Arduino board to communicate (in turn) with many devices, or other boards, while using just two pins of your microcontroller. As the clock line changes from low to high (known as the rising edge of the clock pulse), a single bit of information - that will form in sequence the address of a specific device and a a command or data - is transferred from the board to the I2C device over the SDA line. The I2C protocol involves using two lines to send and receive data: a serial clock pin (SCL) that the Arduino Controller board pulses at a regular interval, and a serial data pin (SDA) over which data is sent between the two devices.
