Serial communication in this example is from the computer to the Arduino, but it could easily go the other way.
#ARDUINO SERIAL PORT SETTINGS HOW TO#
In this tutorial, you learned how to communicate with an Arduino microcontroller using C# through a. Finally, consider setting the initial value of the checkbox to match the current state of the LED. You could also add error handling or serial read/write timeout limits. To improve this application, consider adding the ability to select the appropriate COM port from the desktop app's user interface using a ComboBox dropdown. private void Window_Closing(object sender, e)

If your requirements are different, feel free to make the necessary adjustments. Configure the Window_Closing event handler to close the serial port when the window is closing. Private void ledCheckBox_Unchecked(object sender, RoutedEventArgs e)įinally, for this application, we can leave the serial port open until the window is closed. private void ledCheckBox_Checked(object sender, RoutedEventArgs e) To keep things consistent, we will write a 0 when the box is unchecked. Our ledCheckBox_Checked handler, then, should write a value of 1 to the serial port when the checkbox is checked. Recall that the Arduino is listening for a 1 in order to turn the integrated LED on. _serialPort = new SerialPort("COM3", 9600) Again, my device is connected on COM3, so you may need to change the highlighted line in your code.
#ARDUINO SERIAL PORT SETTINGS INSTALL#
If you don't have it installed, you will need to install and include the System.IO.Ports namespace. First, open and configure our serial port. You will notice a few event handlers we need to define ( Window_Closing, ledCheckBox_Checked, and ledCheckBox_Unchecked). For the purposes of this tutorial, I added a simple CheckBox element from the ToolBox in MainWindow.xaml. Now, launch Visual Studio and create a new WPF project.

Any other character will turn the LED off.īe sure the correct Com port is selected and then compile and upload the sketch to your device. When the Arduino microcontroller reads a value of 1 in the incoming serial buffer, it will drive the LED pin high and, thus, turn the LED on. Serial.begin(9600) //initialize serial comms On the Arduino Uno, the built-in LED is tied to port 13. Open up the Arduino IDE and create a new sketch that looks like the following. It will then toggle the LED based on the value of the data received. The Arduino sketch will continuously read from the serial port, listening for input from the computer loop. Program the Arduinoįor this application, we will toggle the on-board LED based on values received through the serial port. For communication between the Arduino and our C# program, we will use the serial COM port. We will be using Visual Studio to write a WPF application that will interface with the Arduino. Connect the Arduino to your computer via USB port and take note of the COM port it is connected through. Getting Startedįor this tutorial, you will need an Arduino board and the Arduino IDE. NET to extend the functionality of your Arduino device? In this tutorial, we will be writing a WPF desktop application to communicate with an Arduino Uno board connected through a USB port to your computer.
