Code: Sub tester COMport = FreeFile Close #COMport 'open comport, need to change com number to correct one Open 'COM4:9600,N,8,1' For Binary As #COMport 'send data to arduino, number on the end the important bit 'Put #COMport, '085' Close #COMport End Sub So my arduino code works fine i have no issues with that. The problem is the communication piece. If i start arduino serial monitor first to establish communication, then go to excel it works fine. But i cannot communicate properly with the arduino directly from excel after a fresh reboot. I appear to be missing a handshake of sorts with the arduino upon restart. Any idea how to solve this. Preferably via excel only without a 3rd party application.
Before this I’ve 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 I’m 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. I’ll be using the Express edition since it’s free. Who doesn’t like free stuff?

П™‚ In this demonstration, I’ll be creating a simple program in Visual Basic 2010 that allows the user to turn an LED On or Off on the Arduino. The LED is connected to Digital Pin 13 of the Arduino Uno. Don’t freak out cause I didn’t use a resistor for the LED. This particular type of LED I bought has very high impedance, I’m 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 I’ll be sending from the computer will actually be in ASCII. Here is a screenshot of the program written in Visual Studio 2010 Express. The serial port baud rate is set to 9600 and the Arduino Uno is using COM4. Visual Basic 2010 comes with the SerialPort function, so it’s pretty simple to program. Here is a video demonstrating how the program and the Arduino work together. Thanks for the quick response!, I really hard time to figure it out, hope you could help us.
(sorry for poor english) I will let you show our program on temperature sensor separately from humidity sensor in Arduino here’s the site the temperature could already read in the GUI from Visual Basic, and now our problem is how to combine those sensors in one code for arduino. Here’s the picture of our GUI in VB we use ListBox for values we received from arduino. And here’s the code for our VB we set it a timer1 so that for every second the values will display in ListBox when I try to build only the temperature will display, could you help me with this problem?
