You have analog inputs to your Arduino. Look into current transformers like this. You can find a whole bunch of them at DigiKey or Mouser. The advantage is that you can generate an alarm also if the pump motor is seized.

Well done  often it's about starting at one end of the puzzle and having persistence .. and if that fails, know when to re-shuffle what you're given and change tack

I am also very proud of you 
I can't even remember the last time I had to take out my pitchfork

The toothbrush was invented in the south otherwise it would be called a teethbrush.
I'm not sure how many cookies it makes to be happy, but so far it's not 27.

See hair! What part does this play, if any, in the out-comb of anything? Time, perhaps,to brush-up on your punmanship?
P.S.: is a follicle just a small amount of silly behavior?

Dirk Ehlert - Elements[^]
This week's SOTW was brought to me by @Nelek 
I didn't know Dirk Ehlert, nor his project/pseudonym(?) Dos Brains (under which this song is also known).
Looking at it, Dos Brains may be a publisher, but they do have a Spotify account with LOADS of albums, and Google also says they're a musical artist.
Anyway, Dirk Ehlert makes music for film and media, probably many of which are trailers.
I see his work includes The Hunger Games, Assassin's Creed, CSI: Miami and American Idol.
His music is pretty epic.
So if you like epic soundtracks and trailers this may just be your thing.

I like this very much. Should be used in an "epic" movie of sorts.

If you haven't heard of it, you might like Arnaud Rebotini's - "Pagan Dance Move". It is a little risque for the Lounge, but you can look it up on YouTube.

That one's awesome, straight into my playlist!
He was in a death metal band, so I guess that explains the video
Edit:
I see a lot of Immortal in the video by the way, and if I'm not mistaken also Mayhem and Gorgoroth.
Listened to all of them a lot in the past, and still do from time to time.

PS - this vid[^] isn't so risque, and was put up today! What timing!

I've built a few simply projects with the help of tutorials. I've been doing java as a hobby for several years. I know JavaFx, Android, and I"m in the process of learning Spring. I'm familiar with Python, HTML, XML. About 7 years ago I studied and therefore know, to a lesser extent SQL C++, JS, PHP, since I mostly forgot those languages. I've been seeing a lot of job postings asking for Java with Android, Spring Framework and Node.JS or Angular. Node and Angular Javascript. I did a few weeks of lesson on those frameworks a about 4 years ago, but mostly forget. Why do they want that? How important is it to have exactly what they want? I'm still working on learning Android and Spring. Is it imperative to learn Node to find a job? As you can see in my github account I've have hundreds of projects big and small in Java, and a few in Python

Jobs where they are asking for both Java and some combination of a web framework along with JavaScript/TypeScript tends to show one of two things.
1. The job is for a "full stack" developer. This means that the developer is meant to be as comfortable coding at the front end as they are with coding at the server.
2. The person doing the hiring, whehter they are the manager, HR team or recruiter, don't have a clue about the technology and have just thrown everything in.
If the actual job description indicates that all of the code will be at purely at the client side, or the server side, this is a pretty good indicator that option 2 is in play here.

The two most important questions are the ones we cannot answer. Although Pete has given a couple of good suggestions. The only way to get definitive answers is by applying for the jobs and seeing how far you get. If you know of a reputable recruiter then go and talk to them, explain what you have to offer and see if they can help.

And that's much more difficult as one think at first glance

So true, my own experience is that most of them are a waste of space.

You can always check the job descriptions/requirements to see whether the company provides training on the job. It doesn't hurt to get some base experience with those technologies (Angular, React, Vue) so you're not completely clueless when you go into the role, but most companies will provision for people needing to learn technologies. If it's a senior role, there might be more of an expectation to have that experience already.
This is a big problem some graduates face when entering the developer market, the list of requirements can seem overwhelming and off-putting. Just remember that just because a job has listed 20 different requirements doesn't necessarily mean they expect you to have experience in all of them, you can always ask about whether they provide training and explain that you'll need time to acquaint yourself with the technologies.
We hired a Java developer on the back of his strong knowledge of Java, but he had little experience with Spring, Angular, Oracle etc. and we simply allowed him to learn on the job. And after getting hands-on with our software he took the time at home to build his own projects and learn more about the technologies we're using.

If the job requires JavaScript, then it is very important.
If the job doesn't require JavaScript, then it is not important.

Now your question about 'why they want that' with a variable list of frameworks? Very often it comes down to supporting some legacy code - maybe freshly written by someone who's moved on; maybe they've been in use for years and someone's retired/fired/moved on.
It should be no surprise that their needs are (very often) based not on what they want but what they already have. Perhaps, it also includes someone's wish list or HR's/management's uncontrollable desire to use the latest buzz-words.
Best Java jobs? Sometime, maybe they're available at Starbucks.

I'd rather have someone on my team that: 1) knows how to solve problems, and then 2) knows a few languages to aid in solving those problems. If a person knows a few languages well, or knows a lot of them just below the surface, but they have no reasoning/problem-solving skills, software development might be the wrong path for them.
