thank you for sharing, first-ever Arduino project with (for me) it was about time.. It is ultra fun, need to test a lot of the other types I bought. Once more thanks a lot! I would be even gladly see some really indpeth tweaking of profiles of Neopixels with Arduino in the future. :)
I am increasingly impressed by the simplicity of the Arduino programming environment. Have you ever tried the RaspberryPi? I suspect it may be more difficult to programme, but potentially have more versatility as well.
It would certainly have more versatility since it has an order of magnitude more processing power, but I can't comment on its ease of programming since I have never tried. I am slowly leaning Python though, so it's definitely a possibility.
@@SimpleElectronics I pre-ordered one when they first became available in Britain from RadioSpares in summer 2012--and have never done _anything_ with it. I am not even sure I ever powered it up--quite a waste to say the least! I got it at the time because I heard it would be possible to fully emulate in hardware the old Acorn RISCOS computers using the RaspberryPi. Sadly I never heard much more about that, so don't know where the project stands or if it even went forwards. When it comes to scripting I am personally not a fan of Python over Perl. The weird white-space-as-syntax has always put me off along with the immutability of variables paradigm. Sadly there is not a really good Perl IDE while Python is very nicely integrated in to VisualStudio. No doubt therefore at some point I will be forced to make the jump unless something changes.
Hey, I appreciate you gave my channel a shot, I saw he shouted you out too, so I'll have a poke at your channel in the next few days (have to prep courses for my students for tomorrow - but your shit looks pretty nice, from a cursory glance)
Power-wise I would say that 5 is already pushing it, but it depends on the input of the Arduino; if its being fed from a 5v USB maybe you can push that to 10, maybe! but if you are using the arduino's regulator to regulate down from say 12v, only a couple would be safe. also, I'm not sure why you mention a mosfet, the arduino can drive the pixels no problem, it's the current supply the problem!
Simple Electronics well that’s the thing. I’m having a hard time finding concrete info on what external components are needed to drive neopixels off of a 3D printer mainboard (which is essentially an Arduino). I’m not sure if there’s a difference with how you drive neopixels vs LED’s, whether it’s appropriate to use digital vs analog pins, when a external mosfet is required vs when I can just run a external power to the neopixels and signal ground to the board, etc.
The printer board is running off a 24V power supply and then there’s 5V pins on the board that I know can’t handle any real current so I would be running separate lines from the 24V power supply to a buck convert and drop it down to 5V while pulling as much current as I need. I want to drive 2x 200mm strips up the sides and a small bar under the nozzle.
Just a quick play with Adafruit's Neopixel library, these modules are fairly inexpensive on Ebay, Aliexpress or whatever you choose! Enjoy!

FastLED library has some cool examples also.
Hmm I may have to mess with that next time, thanks!
@@SimpleElectronics "Gadget Reboot" just did a video of the library. Check it out.
what sort of wattage does the rings output as a light output.
approximately 0.4W per LED
Nice start brother
Would love to see a ring and a neopixel strip in parallel. Is there anything out there on this type of build? Great video by the way!
not that I know, I should order some strips

@@morelenmir just install a nice Raspbian OS and go browse the internet with it, at least it won't be collecting dust!
@@SimpleElectronics Good point! I may give that a shot!
I'm here on recommendation of Junk From Work's channel. He gave you a shoutout so here I am. Pretty cool channel you have here!

What do you think the maximum safe number of neopixels are to run off of the Arduino before using a separate power source and a mosfet?
Power-wise I would say that 5 is already pushing it, but it depends on the input of the Arduino; if its being fed from a 5v USB maybe you can push that to 10, maybe! but if you are using the arduino's regulator to regulate down from say 12v, only a couple would be safe. also, I'm not sure why you mention a mosfet, the arduino can drive the pixels no problem, it's the current supply the problem!

i use 60 led directly from arduino and plug the arduino to smartphone charger or laptop USB and its fine
Wait this isn’t a lightsaber!
it helped, thank you
Isn`t this strip GRB not RGB?
They seem to be!
Nice 👍🇫🇷
