I am trying to send some information to an Arduino board by using a VB.net script. Only, I have to admit I'm a bit of newbie in VB and I am a little stuck. I have set up a boolean toggle so that if the toggle is set to true, then it should send an 'H' to the board and set Pin 13 to High. If the toggle is set to false, then the script will send an 'L' to the board and turn pin off. I can load the Physical Pixel example to the board so that when it receives either of these letters, it will either turn the Pin on or off. Ge appliance rewards. So basically, what I need to do is to somehow send a letter to the board. But, I'm a little lost on where to even begin. Nov 23, 2011 VB.net sending and receiving data to or from PIC through RS-232. Visual Studio Languages. You can send the character 'A' to the serial port writing routine and the system will write the corresponding binary data to the serial port, but you need to be sure that the correct binary data for a particular character is transmitted. This is the snippet Send/Receive Data Via the Serial Port Using MSComm Control on FreeVBCode. The FreeVBCode site provides free Visual Basic code,. This link was suggested as a starting place (but I'm not actually using Visual Studio or Express. Download film magi season 2 episode 25 sub indo. I'm using a plug-in (called Grasshopper) for a 3d software package (called Rhino). You have the ability to write your own custom components through VB, which is where I got the idea to send data directly from this plugin to the Arudino. If someone could help me with some basic instructions on where to begin, or how to do this simple example. I would greatly appreciate it. Cheers, Andy This is the code that is setup in the plugin. The message that is fed into the component is either the letter 'H' or 'L'. This letter should be sent when the activate boolean value is set to True. This is great! Your sample code worked perfectly. I know this was a very basic example, but my main hurdle had been how to get any data transmitted from Grasshopper to the Arduino. I can now change the toggle and turn on the LED. But now, the sky is the limit. BTW, here is a link to the main Grasshopper page. And here is a link to the scripting page in Grasshopper: As I mentioned, what's nice about Grasshopper is that it allows you to set parameters that control 3d objects. Now, that I can successfully talk between Grasshopper and the Arduino, I can easily design something in 3d in the computer and have it also output the data in realtime to a board which will also control the physical environment. I'm much more proficient in Grasshopper (vs. VB.net) so if you have any questions regarding the interface, don't hesitate to ask. ![]() Thanks again. I have a follow up question. I have successfully sent data from Grasshopper to the Arduino through VB. But, what if I wanted to reverse the flow of information. What if I wanted to send data from the Arduino to Grasshopper (through VB). ![]() Here's a simple example. Let's say I have a photocell hooked up so that when I turn on the serial monitor, I get a stream of voltage information that is coming into the computer. How would I read that information in Grasshopper (again using VB). The problem in the past with Grasshopper has always been with reading information into the program. It has no problem streaming data out. But, it only refreshes the algorithm if something has changed in Rhino or in Grasshopper. And since nothing has really changed in the Grasshopper definition or in the Rhino viewport, it doesn't know to refresh the solution, and thus get new information in from an external file. In the recent release of Grasshopper (just 2 weeks ago) there is a new timer component that will refresh the solution based on any time interval that you give it.
