So if i use this room spray, which has many poisonous gases as we can see, uh the ingredients. #Servo motor arduino labview serialSo right now, if i just open up my serial monitor, i can see the values at 92.93. #Servo motor arduino labview codeSo here what im gon na do is, i will just upload this code in arduino, and this code is very simple once it will just see the analog values from the mp135. So here we have mq135 gas sensors, which is to detect usually carbon dioxide or other poisonous gases. So now here this time we have just changed our sensor to do another exercise so that we can see if we can acquire other sensors data. Similarly, if i just increase with the distance, it is consistently increasing or decreasing the distance, so right now anything which is just requiring and the data in arduino, it is just simply shown in labview, so it means that we can use any kind of arduino code and Acquire the data and then read it in labview and then manipulate the data by using some various function, which can be very useful in labview. It is just showing me 29 centimeter now, if i just playing in front of it something like my breadboard now it is reducing the distance. I will again refresh and then select the port and run my program here. So so now what we will do is we will just upload the code again in here we can see the code is just uploaded and now, without going to serial, monitor in arduino, we will just use our labview program now. The main point to note in here is how we will acquire the census data from arduino, so as we have seen that, since the serial monitor is reading this value distance, so it is the value in serial loss print distance. So read the buffer, so now what i will do is now the main thing. So here is the stop button and then similarly, i have to read the data so ill, create an indicator in here. I will use a little bit of delay like say, 500 milliseconds, and then i will use a control function to control the while loop. We can also simple error handler in here, but right now i will just give it left it, and now i can just increase its space for the battery data position purposes. So i will connect this at the read end and then i will just connect it out with my close function. It will check how many bytes or what is the data is receiving at the port. Then i will just connect it with the bytes at port, which means that it will read all the bytes after sending this command. So now i will just simply connect it with my right function and Music. So it means that now it is one minute or i can say 100 100 seconds it will take to stop or reset or the timeout. So what i will do is we can increase this time by adding zero at the right hand. If there is no connection between this time uh this vi will time out. So the 10 seconds here is the time of time out. I will just first of all: i will give the control as the resource name at which the at which home my arduino is connected, and then all of these things will be the same, um and but ill give we can give another. So what i will do here is, i will use a while looping here to enclose these functions right now, so i will just connect. And here i can get the configuration and import sub vr and then what i will do is i will use, write, function and then read function and then close function from here, and i can also use these bytes at port, which is im just making a very Simple right now serial communication uh vi between the labview and arduino. Ill, just pin it down in here and lets just go to visa or serial monitor. So for that purpose lets just go to our block diagram here and then i will go to uh instrument, and here i have instrument drivers, visa gpib and serial communication. So now we will just jump on to our labview programming environment to see how we can acquire this sense of data that we have seen in the arduino serial monitor into labview. So after making its connection diagram, we will move on to its arduino code, since, in serial communication with arduino, we must need an arduino code which will run uh to use basically to control motor or acquire any census data, but all well do is in labview is To acquire that census, data which is starting from the arduino basically so lets just start from here. Diagram with arduino will look like this. So for this purpose lets just start from the very basic sensor, which is ultrasonic sensor here and its connection. Today we will do another exercise on serial communication between arduino and labview, so the purpose here is to acquire some census data with arduino and then display it on labview for a serial communication.
