The following background story: I had an accident with my car, and my right xenon headlight developed a leak. The water that got in it caused the entire headlight to stop working, including all of its functions. Now, my question is about the headlight's main control unit. Can this be saved by cleaning it with…
I have a strange problem with an anemometer – the measured value keeps jumping back and forth without any discernible logic. The revolutions are measured with a Hall sensor TLE4905, which is a digital Hall sensor that only reacts to one of the two poles. The test setup on the breadboard works so far that…
So, like this. Because I don't need Samsung TV Plus and Disney+.
In the picture here are rods that probably have nothing to do with the control system. They go to the piston valves on the locomotive. What are they for?
What exactly is the point of ever-increasing minimum wages? Yes, wages are getting higher, but prices have also risen massively. So, what is the point of forcing a rise in the minimum wage if it only makes prices more expensive, and while they nominally have more, everything is eaten up again by costs? At some…
Hello, does anyone know how a railway turntable is operated? Do you just turn a wheel to power the motors, or is there a more complex control system that also stops the turntable at the respective tracks? Otherwise, it would be quite difficult to slow the turntable down from track to track.
I would like to operate an Arduino with 12 or 13.8 and control two 12V motors with the Arduino – with a 4-channel relay card whose inputs are separated from the 12V circuit by optocouplers, this also works, but not with a simple MOSFET. But I would rather use Mosfets than the already decoupled relay…
I have connected a potentiometer to my Arduino and convert the values into a scale from 0 to 100: // Variablen für Potentiometer int Potentiometerwert = 0; int Potentiometerminimum = 125; float Potentiometerproz = 0; int Potentiometeranz = 0; int Potentiometermax = 896 – Potentiometerminimum; int Potentiometerdifferenz = 0; int Gradkorrektur = 0; //Potiprozent berechnen…
Can this controller use the ARGB function so that I can display multiple colors at once on one RGB string? https://www.amazon.de/dp/B07R32CS17?ref_=as_li_ss_tl&language=de_DE&linkCode=gs2&linkId=003b5369a39b53a310bf0e42b140be2d&tag=smarthomeso05-21&th=1
Hello! I need to build a control circuit. I don't know exactly how it works yet, but I have the materials list and a photo of the final result. I'm finding it difficult to plan the circuit, especially because of the two load contactors. I usually only build with one load contactor. Can you help…
There are different perspectives and explanations. If possible, please answer in detail and cite sources. Maybe also compare with (MOS)FETs etc.
