Basic Principles of Arduino Serial Communication Communication Methods and Implementation Serial communication is a method of transmitting data in a bit-wise order. In Arduino, serial communication is mainly achieved through UART (Universal Asynchronous Receiver-Transmitter). UART utilizes two pins, TX (transmit) and RX (receive), to complete the data sending and receiving tasks. Data is transmitted in … Read more
Of course, below I will provide a complete example of Arduino serial communication. This example will demonstrate how to perform simple data exchange between Arduino and a computer. We will write a program that receives characters from the computer and performs different actions based on the received characters. At the same time, Arduino will also … Read more
Arduino Uno provides serial communication functionality, allowing it to exchange data with a computer or other microcontrollers. Serial communication is a very common feature in Arduino projects, often used for debugging, data transfer, and interaction with other devices. Below is a detailed introduction on how to use the serial communication feature of Arduino Uno. 1. … Read more

4.1 Basic Concepts of Serial Communication Serial communication is a commonly used communication method, which refers to data transmission between devices through a Serial Interface. There are several basic concepts of serial communication: 4.1.1 Serial Communication Serial communication refers to the transmission of data bit by bit, transmitting only one bit at a time. Compared … Read more
To master the STM32 microcontroller, one cannot do without serial communication. Serial communication uses a protocol called the serial communication protocol to manage data transmission, which controls the data flow during transmission, including data bits, baud rate, parity bits, and stop bits. Due to its simplicity and ease of use, serial communication is widely applied … Read more
Embedded electronic devices are collections of various circuits (processors or other integrated circuits). In order to exchange information between these independent circuits, they must follow the same communication protocol. To accommodate different needs, engineers have defined hundreds of thousands of communication protocols, which can generally be divided into two categories: parallel or serial. 1. Parallel … Read more
1. From Polling to Interrupt Many students prefer polling over interrupt-driven operations. Is this related to our nature? Everyone likes to have everything under control and dislikes being interrupted. We often have experiences where we are talking to someone and suddenly receive a phone call, and after the call, we can’t remember what we were … Read more
Arduino has a rich set of external interfaces, and the biggest difference from Raspberry Pi’s IO ports is that Arduino has analog input interfaces that can measure analog values on IO ports. The communication scheme between Arduino and Raspberry Pi via serial (Serial) generally has two methods: one is through Raspberry Pi GPIO serial communication, … Read more
