Please refer to the following tutorial for reading from serial port at arduino side: https://learn.adafruit.com/adafruit-arduino-lesson-5-the-serial-monitor/arduino-code You will then have to code in C# side to write to the serial port. Please be aware that this all works ONLY WHEN the Arduino is physically wired to the computer.
