hello guys… i am facing problem regarding processing 3… we are doing final year project in which we are doing structural health monitoring by using strain guages. now being a civil engineer i am not capable of writing code in processing software to get data from ardunio with which strainguages are attached. can u people help me to write code to recieve data from dtrain guages…

[image] shariqqureshi: write code to recieve data from dtrain guages Hi. You want the arduino code? Isn’t it easier to search on the Arduino forum? What are you using as hardware? A strain gauge in a quarter Wheatstone bridge formation with the HX711?

we will upload code of strain guage from arduino software to arduino chip and then want to receive output in processing software… first of all we are doing it on small sacel using strain guage bf350 strain guage attached with steel rule… after gettting results… then we wil perform it on large scale on real bridges… so we need code of processing software to get data from these strain guages…

[image] shariqqureshi: receive output in processing software So how will the data be transferred? If you are going to install it on bridges you will need wifi at the least, or are you going to store it on SD and need this data to be displayed in sketch?

There is a related topic from @shariqqureshi : [image] Visually show beam in processing Project Guidance in our final year project our wants us to show beam in processing software… i.e if we apply load on he beam in reality it will be visible in processing software also show us deformation recorded by strain guages … can we do this in processing software ??? ??? :slight_smile:

You can‘t get Strain gauge Output as Input in Processing, because Processing doesn‘t read that, your Arduino does. What you can do is to get data (serial) from your Arduino into a Processing sketch. Here‘s a link to how that is done : https://forum.processing.org/one/topic/sending-data-from-arduino-to-processing-serially —————— @glv i think he knows about that, since he‘s the one who posted that :sweat_smile:

@shariqqureshi Here is a resource for you: https://itp.nyu.edu/physcomp/lessons/serial-communication/interpreting-serial-data/ :slight_smile:

[image] Lexyth: @glv i think he knows about that, since he‘s the one who posted that :sweat_smile: That was for the benefit of the community assisting him with this topic. Good catch! :slight_smile:

In the other post(and I hate people posting more posts about same subject), he said he had to show some work tomorrow at the meeting. So I think that kll’s help was sufficient Anyhow, a strange story for someone’s final year using such a cheap sensor. This will only work on a very flat polished surface attaching with the right glue. Even then data will come out very noisy.

What alternative would you suggest, to not have to use strain gauges? (I‘m asking, cause i‘m working with strain gauges on a project and i‘d be nice to know the possible alternatives :sweat_smile: )

Thanks … for ur assistance… i will write code and if it shows some error then i will tell u…:blush::blush::smiling_face_with_three_hearts::hugs::hugs:
