Thank you! Yes, they are extremely widespread. I am also planning to use them in some future projects, but they are not that cheap and they are also a bit bulky. Sometimes a tiny limit switch does a "better" job due to its size.

so what is the accuracy of capacity sensors? If I want to measure a variation of distance 0.5mm would it work or an inductive would be more accurate?

This is not a distance sensor but a proximity sensor. I guess their accuracy depends on the model, so I would suggest you check the datasheet of the product before buying it.

did not expect you would be answering so promptly, my respect for your communication with the followers. I do not want to measure the distance but to detect proximity whithin a certain distance which in sense is a kind of distance measurement but indirectly. So if I intentionally calibrate the sensor to detect the obect at 3 cm, what is the minimum distance the sensor will not detect the object? Will I still detect it at 3.5 cm? Thank you!

One of my principles is to try to communicate with my viewers as well as possible. So yeah, I am trying. The sensitivity of these sensors is quite good, and typically, you can adjust it with a potentiometer with a high accuracy. Unfortunately, I don't have the exact numbers, but if you can wait a day or two, I can measure it for this specific sensor. Otherwise, I still recommend referring to the datasheet.

@@CuriousScientist I appreciate that, don't worry, I looked up online for acurracy of 0.1mm sensors but I think it is not called like this. It is either resolution or something else. Data sheets would provide the range of detection but that is something different.

@CuriousScientist

Hi and thank you! Not _this_ exact one, because this is a capacitive one. But there are similar, inductive proximity sensors. Same housing, same switching principles, but the sensing is done on inductive/magnetic basis. But if you want to sense something magnetic, or based on magnetism, I also suggest you to look at Hall-sensors. They are very cheap and they also detect magnetism, so the presence of a magnetic field can trigger them.

Maybe i'll only detect magnetical material, let's see. Thanks for the help!

Hey I am trying to build a circuit with a hall sensor, arduino uno, a motor and a push button switch. When the button is pushed, the motor should turn on and then when the hall sensor detects the magnet, the motor should turn off. Another press of the button should the reverse the direction that the motor spins. If I want the motor to turn off when the sensor detects a magnet do I need to use a PNP sensor?

Hi! You have to program the logic anyway, so it doesn't matter if you have a PNP or NPN switch. You'll determine the behavior in the code.

@@daniellehenderson5272 Hi. If I am not wrong, the NPN proximity sensors go LOW when you detect something with them. You do not need to fiddle with the INPUT_PULLUP option. Also, you might need an additional circuit for your sensor if the operating voltage is more than 5 V. You cannot directly connect a 12 V or 24 V proximity sensor's output to your Arduino's GPIO pin...

Hi, I would love to know how to do this with acceleration and deceleration. runSpeed() does not seem to allow this function which is crazy for an Acceleration library. Is it possible to have a gradual start and stop speed initiated by a sensor input where you can't use runToPosition()? You code explanations are brilliant BTW! Thanks
@CuriousScientist

Hi! You should read the very well written documentation of the library. RunSpeed() intentionally doesn't have acceleration. You should use run() if you want acceleration. Also, check my more recent videos where I have better code written using this library.

I basically just need to run my motor in either direction depending on a sensor input, exactly like you are doing with the prox sensor but I need acceleration to keep the transitions smooth. Swapping runSpeed() for run() didn't seem to change anything.. should it work that easy or do I need to change something else too? I'm using your code, the same as in this video.

Acceleration also needs target position instead of speed. So you will need to use the move() or moveTo() functions to determine a target position. You should give some larger number as a target than the number of steps required to reach the end stop switch. Then, when the switch is reached, you stop using the stop() function which will decelerate to zero, then give the same (slightly larger) target with an opposite sign and let the motor run in the opposite direction. Obviously, you should have another limit switch on the other side. Actually, the code I used in this video should help you: kzitem.info/news/bejne/wJukvqyZe4aAl4I You just need to modify a few conditions and it is done.
