RE: PicoLab_EnvMonitor : a learning journey on LabVIEW - Final

I got some feedback from Jan Cumps about the LabVIEW projects I did. I would like to share the updated project: NTC thermal sensor controlled FAN system.

1. I split the VISA resource into two blocks in my previous flow. I did notice that. I knew it would not do good things for the project. However, I did not know why. The overall project still functioned as expected, so I decided to push the split VISA source with two "close" blocks at the final blog. I would like to listen the feedback about that. Jan Cumps did find the non-ideal flow on the LabVIEW projects. Good catch.

Here is the original Jan's comments:

little watch-out: you split the VISA resource to two blocks in your flows, and then end both branches with a Close block.

It's the same single VISA resource, you should only close it once. Either join the two branches at the end, or only continue one and close it.

2. I updated LabVIEW project after Jan's feedback as this:

and

3. Updated NTC short breadboard circuit into a soldering prototype circuit. I like soldering prototype circuits for the bench testing. I did find some time last weekend and updated the NTC thermal sensor circuit with copper paper, SMD resistors/capacitors and 30 gauge wires as below:

The copper paper really helped with overall prototype circuit routing.

Here is the updated NTC/FAN LabVIEW bench testing:

and

It took me two iterations to build the updated NTC thermal sensor circuit with copper paper and SMD parts.
