MOSI – Stands for Master Out Slave In.It is the line that sends data to the Arduino. MISO – It is abbreviated as Master In Slave Out.Hence, it contains four lines that are common for all peripheral devices. For example, in the Arduino Uno, the SPI communication protocol is handled by its microcontroller. Usually, an SPI connection is run by a microcontroller that controls other peripheral devices. Why? Isn’t serial meant for long-distance? But the restriction is it will work only in short-range communication. What does that mean? While Arduino uses SPI to communicate with other devices quickly.
It is asynchronous as well as serial data protocol. SPI is abbreviated as Serial Peripheral Interface.
They are asynchronous and can send data as a series of pulses serially. Hence, it requires two arguments that represent both the directions of data communication.Īll devices have their transmitters and receiver. It allows two devices to communicate with each other. UART is abbreviated as Universal Asynchronous Receive Transmit. Let’s take a look at the following standard communication protocols. Moreover, there are hundreds of protocols available for performing this data exchange between an Arduino and other devices by using both wired and wireless pathways.
What are the methods of communicating with an Arduino?Ĭommunication is an important process for transmitting and receiving data from and to the Arduino while doing projects.
