I'm here to ask for help as an ultra beginner using hardware in a development projet.
As a school projet I wanted to do a "cocktail machine" a real simple one so I followed this tutorial : Arduino - Controls Pump | Arduino Tutorial (bought the exact same tools).
And.... It worked ! I mean if I put the pump's tip in the water, it does work so you could say it works but my goal is to make water or any fluid running through a tube.
So I bought Silicone ones and I felt like the pump isn't powerful enough, the water doesn't go all the way... Reducing the size of the tube doesn't do the trick either so I figured, maybe the silicone tube is too large.
Before buying another size of tube, I wanted to try with something narrower so I used a straw but unfortunately, same result...
I thoroughly checked that no air could pass making the suction uneffective & had no problem with air leaks.
So I was wondering if maybe anyone could help me with that, or has any idea of anything I could try to make this work !
Thanks for reading, looking forward to answers and help !
(Sorry if this was already asked, maybe I didn't check well enough...)
You need 12V >500mA power supply, or 8AA batteries in series.
And the pump has to be immersed in water or at least very short suction line.
The output line can be longer
Get a good power supply and try with the shortest possible suction height.
This pump is not designed to suck vertically, not the ideal pump for that purpose
Yeah sure ! Figuring I didn't detail that much the "cocktail machine" I'm trying to achieve.
So my goal is to have a mobile app connected to my arduino (not sure yet wether I'll wire it or use bluetooth) to select which cocktail I want. Upon selection, It'll start a sequence to deliver the liquid in a glass.
I'm not quite sure about how it would be in the end as I don't have much experience in this domain yet though !
Yeah I'll try vertical pumping with mine one last time !
I didn't know those pumps existed that great, exactly what I was looking for in the first place ! And yeah I'll buy a better power supply if needed, thanks a lot !
Oh right, rn its for a school project so it's gonna be softs but yeah I didn't think of that ! But at the moment it's "just a proof of concept" so it's gonna be coloured water but yeah for a real one in the end it'll be necessary !
I can do that but I was kinda thinking of adapting to the best way to do it rather than having a definitive idea ! But once I get back to work I'll try & make a drawing of how I imagine it !
Good question ! Actually It's supposed to be a project to use for the school (& I'll redo it for alcohol for myself & friends) but also a project to learn some stuff with arduino & some hardware ! So yeah it doesn't really need a pump in the first place but I really want to use one !
