Fig.5: This is the tutorial scenario. As you can see, you will activate a serial connection between the Arduino board and the PC. On the Arduino board you will implement a sketch that will take care of "to listen" for any value (angle) sent from the PC. From the PC side, instead, you will activate a serial session in a Python shell (but it. Solution 1 There are a lot of possible reasons why this doesn't work: 1) The "net time" command could be returning: "Could not locate a time-server.

The Below code writes character 'A' to the serial port. The first line import serial imports the pySerial module so that your program can use it. ComPort = serial.Serial ('COM24') opens the serial port named COM24. In Windows, Please give the COM number corresponding to your Serial port or USB to Serial Converter instead of COM24. There are three overloaded implementations of Serial.write: Serial.write (val) Serial.write (str) Serial.write (buf, len) The first one sends a single byte, as johnwasser showed. The second one sends an array of bytes, stopping when it reaches a null value in the array. (This would usually be used to send null-terminated strings.).
