Arduino tutorial analogue vu gaugesmeters pwm. Analog Meter (Ammeter/Voltmeter/etc) Control for C# and .NET « Random thoughts along the roadside… UPDATE: See my newest update, which includes a C# Oscilloscope and Analog Meter control! This is another open source C# control that was developed for my Senior Design project. Its pretty obvious what it does from the following screenshot. This is definitely a useful control for some projects, and is released under an open source license. This control implements a simple to use Analog Meter control, similar to old school analog meters used for all sorts of things. Obviously theres a lot more things that could be added to this, but this does what I need it to do at the moment. Its very adjustable as well, with integrated designer support. Usage Add the control to your form, and adjust the Value parameter of the control to move the needle.

Enjoy! Download: Link. Analog and LED Meter. Introduction I've been searching a lot for an easy to use VU meter to use in a simple Audio player/recorder, but I haven't been lucky. I found some samples of LED meters, but not quite what I wanted. It's good that I'm a bit stubborn, but unfortunately I'm also a complete beginner in C#, but that is the language I want to learn so I started my little project 2 weeks ago. This is the result. The Code I started out from a System.Windows.Forms.UserControl. I decided that the size should be calculated from the number of LED:s being used (I started with the LED, and added the analog this weekend), and added properties for LED size and spacing. BackColor is used for the border round the LED:s. The LED:s are made up of filled rectangles, with a solid brush, easy to use and didn't take much time to get working, next I added the possibility to enable a PeakHold with selectable Hold time, and then I wanted to have a vertical version also.

So the only way was the hard way. Using the Code Section Analog. Home | .NET Fiddle. Analog Meter. Download source - 15.75 KB Introduction On the internet I found many projects on analog meters, but few could change their appearance using a custom renderer. Because of this, I decided to create my first control in C#, and use this control in my next projects.

Background To compile this demo you need .NET 2.0 which is available here. The project is developed with SharpDevelop, a free IDE per .NET. Using the Code In the zip files there is a complete solution, but it is simple enough to use the code of the control for inserting this in another project. Control Class The class is derived from System.Windows.Forms.UserControl. Hide Copy Code You can set the following properties at design time: Appearance Properties MeterStyle - Style of the control. Behavior Properties Value - Current value of the control MinValue - Minimum value of the control MaxValue - Maximum value of the control In the next section will describe the renderer class and how it is possible to customize the control draw.

Programming python. Serial Port Programming With .NET - All. We need to include two namespaces in order to use the SerialPort class: using System.IO.Ports; using System.IO; We now need to instantiate a SerialPort object. There are several constructors to choose from to specify different frame formats but in general the easiest to use is the following: SerialPort(string portName, int baudRate) An example of this would be: SerialPort mySerialPort = new SerialPort( “COM3”, 9600); Here I am using COM3 at 9600 baud.

MySerialPort.Open(); mySerialPort.Close(); Several notes: when you use any operation that uses a serial port there is a good chance that an error will occur. //this simply creates a SerialPort object then opens and closes the port SerialPort mySerialPort = new SerialPort( “COM3”, 9600); try { mySerialPort.Open(); mySerialPort.Close(); } catch (IOException ex) { Console.WriteLine(ex); } That’s really all there is for port setup!

Draw a graph with labels in WPF and C# - C# HelperC# Helper. This example shows how you can draw a graph with labels. The previous example Draw a graph with even tic marks in WPF and C# draws a simple graph. This example adds a title and labels to the X and Y axes. To make creating labels easier, the program uses the following DrawText method. // Position a label at the indicated point. private void DrawText(Canvas can, string text, Point location, double font_size, HorizontalAlignment halign, VerticalAlignment valign) { // Make the label.

Most of the method’s parameters are self-explanatory, but the last two deserve a little explanation. Those are alignment values that dertermine how the text should be positioned. When it starts, the method first creates a Label control, sets its text and font size, and adds it to the Canvas control’s children. Next the code calls the Label object’s Measure method. Next the code calculates the position where it should place the Label in device coordinates. This is a bit weird so I’ll say a bit more about it.

C# .NET: Access Data from a Dataset. You now have a Windows form and a Database class that you created yourself. Go back to the form and add four textboxes. Change the Name property of each textbox to the following: txtFirstName txtSurname txtJobTitle txtDepartment Add four labels to your form and place them next to the textboxes. First Name Surname Job Title Department Your form will then look something like this: What we're going to do now is to connect to the database using our class. To add the Form Load code stub, simply double click anywhere on your form that is not a textbox or a label. Because we're going to be adding buttons later, we need to set up variables where all the buttons can see them.

DatabaseConnection objConnect; The variable is called objConnect. We also need a string to hold our connection string from the Setting page we set up earlier. String conString; This is just a normal string variable that we've called conString. Your coding window should now look like this: We also need a DataSet object. DataSet ds; C# tutorial- Basic Syntax. -Using System; is a statement to indicate that you are using a namespace called System. Basically this namespace contains a class (Console) with methods needed to print the values on the screen and read the values from the keyboard. -Using System.Collections.Generic is a statement to use Generic namespace that contains interfaces and classes to allow the user to create strong types collections. -Using System.Linq; is a statement to use Linq namespace that contains interfaces and classes that support query. -Using System.Text; is a statement to use Text namespace that contains classes that represent ASCII, Unicode, UTF-7, and UTF-8 character encodings, convert bytes to characters and vice versa, and manipulate and format string objects.

For now the last three statements are not important, but they will be used in the next sections of this tutorial. -For the console application, the program will start from Main method of class Program that is contained in a namespace (e.g. C# Programming.

C# Tutorial. C# is a simple, modern, general-purpose, object-oriented programming language developed by Microsoft within its .NET initiative led by Anders Hejlsberg. This tutorial will teach you basic C# programming and will also take you through various advanced concepts related to C# programming language. This tutorial has been prepared for the beginners to help them understand basic C# programming. C# programming is very much based on C and C++ programming languages, so if you have a basic understanding of C or C++ programming, then it will be fun to learn C#.

For most of the examples given in this tutorial you will find Try it option, so just make use of this option to execute your C# programs at the spot and enjoy your learning. Try following example using Try it option available at the top right corner of the below sample code box − 1000 C# Programs With Example Code and Output - Sanfoundry.

[C#] to replace the switch-case code and long for a more beautiful manner. The switch-case statement is a branch of commonly used statements we coding process. However, it also called into the Xiao Hebai Xiao He, whenever we asked a have time to add case new branch of hundreds of thousands of lines of switch-case code segment, we have to code readability and maintainability continuously decreased and headache trouble. In fact, we can have many ways to avoid this branch of switch-case code section and long, so as to write more beautiful code. In.Net we can simply decomposition switch-case code. Select a common example: module uses switch-case to process the received Command If we define the following 10 CommandID now. 1 /// <summary> 2 /// Definition of commands. 3 /// </summary> 4 enum CommandID 5 { 6 Abs = 1, 7 Sin = 2, 8 Sinh = 3, 9 Asin = 4, 10 Tan = 5, 11 Tanh = 6, 12 Atan = 7, 13 Cos = 8, 14 Cosh = 9, 15 Acos = 1016 } CommandID Here we define a CommandHandler1 class to handle these commands.
