That is a really vague question. I suggest you head over to an online retailer that sells Arduino and accessories. They should have bundles of solar panels and batteries (and controllers) or provide info on compatibility.

It's really hard to troubleshoot in comments. Can you upload code? Can you make it blink an LED? Make sure you can do that first, then troubleshoot the code for the GPS. You may be using incompatible pins on the Mega?

@@MarcdeVinck The Blink code works. Uploading the code is difficult.

There is no easy way to calibrate it. You are most likely better off with a 9DOF sensor as the FSR is more fragile.

Of course. And it's simple! Look up serial printing with Arduino.

Please watch the video I go over where to find the code and how to use it.

Filter the results via code if possible. That is the easiest solution. Try averaging the results over time?

The manufacturer should have code. Mine is from Adafruit, they supply the code for the specific sensor.

I used this sensor -- www.adafruit.com/product/1918 The formula you use will be dependent on the sensor.

Sorry, I don’t do any consulting. Check online for some local groups. They may be able to help.

@@MarcdeVinck I need professional help it's last stage of very innovative project

@@akash_here If you need professional help, I suggest you look for a local Industrial Design company or Product Design company to help.

Not too difficult. Just take a reading and calculate the RPM. I have a tutorial on LCD screens too.

You don't need a motor. The slip ring just allows the wires to spin 360º.

@@MarcdeVinck thanks ,I wasn't sure whether these were motorized or not.

@@MarcdeVinck so with these min slip rings how do I attach a motor?

@@anthonytesta3716 They are not.

That's tough to troubleshoot via comments on KZfaq. If you are getting a range, you can easily map that range to what range you would like. I'd have to see the circuit to know. Did you check the polarity?

Slip rings are going to be more expensive that a knockoff microcontroller. Just the nature of scale and manufacturing costs.

@@MarcdeVinck jeah but i wonder that the scale is so much smaller and manufacturing of a microcontroler seams harder than a slip ring.

Yes, that is possible. Just make sure your micro is fast and you can compare response times and amplitude.

Sounds like an interesting solution. I'll have to try that one day. Thanks.

That would be very easy with an ‘if then’ statement. Check out the arduino website for basic code related to ‘if then’

Glad I could help! Thanks for the comment, you made my day.

There are many kits out there, so I don't know. This is a simple sensor and readily available. It can be found in many kits.

Not sure what you are asking. Repeatability, sensitivity, etc. This is not a very precise sensor when used with an Arduino.

Not sure. Please check the data sheet for the product you are sourcing. You can typically find them via a Google search.

I'm sorry, I really can't follow what you are trying to do. The slip ring just allows wires to be rotated infinitely. If you are looking to spin it with a motor, you will need one specific for that task.

@@MarcdeVinck Yes. I'm asking HOW TO ATTACH A MOTOR. You can't attach it axially because the wires are in the way. Does nobody else in the universe want to spin one of these with a motor? What do *you* use them for?

Mine is from Adafruit - - www.adafruit.com/product/464

You need a resistor to get the range and protect the input pin.

No, but a UV sensor can! Enjoy! -- kzfaq.info/get/bejne/rLCTp5OnqZy7h5s.html

The shield I am using requires an AUX port. I picked up an inexpensive speaker for the demo.

Thanks for your reply@@MarcdeVinck

1/4W 1%, but any generic resistor should be fine.

@@MarcdeVinck Thank you very much!

You can use the PIXY! Camera for a "Real product"! It's great! I can't suggest a better sensor without knowing all the details of what you define as better? Larger image, faster shutter, lens, etc. There are lots of cameras available on the market for DIY electronics. Head over to your favorite online retailer and take a look at the specs to find one that matches your requirements. Just keep in mind the real value of the PIXY! is not the camera but the additional hardware and software that supports the camera.

The PIXY Camera system is most likely not the best for that specific use. It's a great camera, but I think you would be looking for an IR thermal camera, which is readily available on the market as an accessory to the Arduino.

MPV runs on an operating system like Linux. Arduino does not have an operating system. The only way you could control it would be to use an Arduino to trigger key presses, a remote spoofer, etc, but not to run MPV. A computer will still have to be in the loop somewhere. However, did you look at Raspberry Pi? That looks very promissing!

@@MarcdeVinck thanks for the response! I was exploring possible alternatives first because the Pi isn't that cheap since covid clogged up their supply lines.

@@csehszlovakze You can get a Pi4 fairly easily now, and the Pi5 was just announced!

The Arduino only needs to be connected to program. Otherwise it runs the code standalone. I guess some UV would go through fabric. Depends on the fabric and the light.
