I added the button and serial port to my form, and then resized the button to fit. For my project, i have 2-3 sensors on the Arduino board, and i need to read the data/information from all the 3 sensors in one Arduino program, and display it out separately on Microsoft Visual Studio. Use Serial.write(value 1); Serial.write(','); and repeat that a few times on the arduino. Read Line().split(','); and then use array[0] to get the first value, [1] to get the second and so on. Some time in the near future I will update this tutorial, covering more on how to read from the Arduino, as well as sending/receiving multiple sets of data. I then added a serialport, and changed the Port Name to COM4. I then double-clicked the button, and it changed to the code view. Until then, feel free to contact me with any further questions : Dthank you so much! my project is due 3 weeks later and my group is still struggling alot and all of us are quite new to microsoft visual studio and arduino! I'm now able to display the data from the sensor i'm using on the textbox. i can't display double data type (example, values like 25.6, 34.8. Invoke(new Event Handler(Do Update));" codes (seen in the attached image). : DIndex Out Of Bounds is called when not enough data has been sent from the arduino to split it correctly. Forms; namespace Air Speed when i run this program, it can display the data and refresh it smoothly, and after a while, the whole form hanged, and informing me that Index was outside the bounds of the array at "this.

I am using a for loop to create instances of the customer class, and when I try to write out their arrival times to a text Box (Just for testing purposes) the text box does not update. This is just a small simulation project for my Computing class. An RGB LED was connected to R Co G B LED Pin 13 12 11 10 Ardunino Digital Pin void setup() int led = 1; void loop() I am trying to read a speed value from the arduino, which is serial.println, I only get the initial value each time I open my program, example when I open my program if the speed sensor is 0.00 that's what it says, but when it changes to let's say a number like 20.5 it still says 0.00, but when I reopen the program, it will say 20.5. Also with it cuts off the first digit sometimes, for example I will have a number like 2.65 for my speed, but when I make i open the program I made, it shows only .65. In this Article, we will learn How to Insert, Update and Delete Record in Data Grid View in C# Windows Form Application. In the above code, I have created data Grid View1_Row Header Mouse Click Event for updating and deleting the selected Record.

In Previous Post, we saw How to Create a simple Windows Form Login Application in C#. When user click on the Row Header of any row then data present in the cell of the row is stored into the Text Boxes.

It is in its early stages, and is probably wrong in a lot of places!
