Before this Ive always used the Serial Monitor of the Arduino IDE to communicate with the Arduino. Actually what the Serial Monitor does is basically reading or sending data through the Serial interface. In my future project, I want to create an application in the computer that allows the user to click some buttons to control the Arduino. Currently, the only programming language that Im familiar with and is able to create a GUI Graphical User Interface Program aka not the white text on a black background program is Visual Basic. Ill be using the Express edition since its free. Who doesnt like free stuff In this demonstration, Ill be creating a simple program in Visual Basic 2. LED On or Off on the Arduino. The LED is connected to Digital Pin 1. Arduino Uno. Dont freak out cause I didnt use a resistor for the LED. This particular type of LED I bought has very high impedance, Im not worried that it will burn out. I wrote a code for the Arduino so that it can receive instructions from the computer. I enclosed the 1 and 0 with inverted commas because the value that Ill be sending from the computer will actually be in ASCII. Here is a screenshot of the program written in Visual Studio 2. Express. The serial port baud rate is set to 9. Arduino Uno is using COM4. Visual Basic 2. 01. Serial. Port function, so its pretty simple to program. Here is a video demonstrating how the program and the Arduino work together. Thanks for reading Download Code.
