Make your own crude Cocktail Machine ryan: I don't get it. The scale zeros before each pump fills the glass, but it measures the weight of the liquid against the zero's value AND THEN allows the predetermined milliliters to enter the glass? But wouldn't you have already poured all the liquid f on the pump to measure that in the first place? Why not just base the milliliters on the weight and have the load sensor ping when the 3000ml is poured to cut off the pump, and start the delay for the next pump? Or is that what it is doing and the wording just didn't come through to me?

Out of curiosity why is the Arduino using a timer to stop the motors instead of using the scale to weigh the liquids? I guess I'm confused as the time it would take to pump x amount of vodka is different from say the time to pump x amount of molasses and it would be easier to find weight by volume then run it through the machine to find volume pumped / time right?

this is an amazing project for someone new to the whole arduino world. i will definitely build me one. im a whiskey drinker and so are my friends the only problem we have is that we top it up different. one has his with water while the other has his with lime. is there anyway you can change the code around so it can memories each persons drink.

why do you use the scale for the liquid starts test only? couldn't you get better, liquid type independent, measurements by using the scale for actually measuring the amounts instead of a timer? or if the timer is good enough, why do you even need the scale, you could just measure the time it takes for liquid to move through the hose.

While 100ml of water weigh exactly 100 gram, that does not apply to any other liquids. They can vary wildly, especially ones with a lot of sugar in them.
Or short:
The Wodka is lighter then water while all the juices should be heavier.
Probably doesn't matter, just curious if you accounted for that.

hello, can you help adding timer function into the code so if the liquid bottle is empty, the fuction will stop after X mount of seconds; to prevent motor from running and burning out. I try the millis) function, but I couldn't figure out how to get the counter start after the drink is requested.

I do enjoy listening to your videos, you are very good with cad and programming. Also its interesting for me to see that everything you do is metric where as Im from Chicago, IL. USA and its mostly imperial/std measuring system, confusing- I wish the world was only metric!

Crude cocktails are the best kind. My favorite is the Purple Passion: Two parts Welches grape juice, one part vodka.

That moment when I realized how dumb I really am lol. Wow dude. U are super smart. U did that! I love it. U should sell it for people like me who would have to watch it 10k times just to get thru part 1 nice job!

Hey great Projekt I want to buy me one to. You talk a lot abut the hardware but how about the software? For me this ist very difficult how I install is and make it work?
