How does Arduino board communicate with Python?
Arduino and Python can communicate seamlessly , and this is one of the most popular ways to control hardware from a PC or log sensor data for analysis. Here’s the breakdown: 1. The Communication Channel Arduino boards usually communicate with a computer through a USB cable . That USB port is internally a serial (UART) interface , exposed as a COM port (Windows) or /dev/ttyUSB0 / /dev/ttyACM0 (Linux/Mac). So the key mechanism is serial communication . 2. Arduino Side On Arduino, you write a sketch that uses the built-in Serial library: void setup () { Serial. begin ( 9600 ); // Start serial at 9600 baud } void loop () { int sensorValue = analogRead (A0); Serial. println (sensorValue); // Send data to Python delay ( 100 ); } Serial.begin(9600) sets the baud rate. Serial.print() / Serial.println() sends data. Serial.read() / Serial.parseInt() can receive commands from Python. 3. Python Side On the Python side, you use...
