Introduction: Cocktail Machine : Smartphone Controlled

You like technology and party ? This project is made for you !

In this tutorial we will create an automated cocktail machine controlled through an android apps !

Everything for cheap price controlled by arduino

The link for the video.

In previous instrucables the cocktail machine was taking a lot of space and could be a bit complicated to make: Here!

Step 1: What We Need:

For this project i will use 8 botlle but you can adapt easily if you want less or more.

-Arduino

-8 channel relay : each channel will be a botlle .(1channel = 1bottle)

-Wire the most important are female to male .

-8 pump the best i found so far.

-Pipe I got 10m.

-Charger

-Bluetooth module

And that's it, just need to add a box for the machine we will see that in the next step!

Step 2: The Structure

Here you can get the plan to make the machine, the software is solid works , if you are based in france this company does it for a fair price ASTC .

If you found some way to improve it please share it !

Step 3: Mounting

Here you can see the major steps for assemble everything.

There is not much to do , once i got got the case , I put the pump on a wood part then screw on the side (see picture)

I did the same for the arduino and relay i set it on a wood part then screw it on the front of the machine (see picture)

That's it you done for this part !

Step 4: Connecting the Relay/Arduino

Let's have a look how to cable everything:

The first picture show how to connect one water pump.

water pump + = RELAY water pump

Negative - = Charger 12V

I used one charger 12V 0.5A(cut the top) the negative goes to each pump (negative) and positive goes to each channel of the relay .

One charger is enough as only one pump will work at the time

Repeat this for the 8 pump.

Arduino :

Also easy you only need to connect the Digital Output to the relay (see schema) and the bluetooth module.

You can personnalize , for me it's like this :

  • whisky DO:5 Relay:5
  • Vodka DO:9 Relay:1
  • ricard DO:8 Relay:2
  • Tequila DO:7 Relay:3
  • GIN DO:6 Relay:4
  • Orange DO:2 Relay:8
  • Water DO:3 Relay:7
  • Coc DO:4 Relay:6

Step 5: The Code

Here you have the code for arduino :

So what it does is : when you will send a cocktail from the app it will send a ''number'' to the arduino.

This number is link to a cocktail wich will activate the pump link to it and done !

Important : When you upload the code don't forget to remove the bluetooth module ortherwise it won't work .

<p>char junk;<br>String inputString="";</p><p>void setup()                    // run once, when the sketch starts
{
 Serial.begin(9600);            // set the baud rate to 9600, same should be of your Serial Monitor

Step 6: The Android Apps

In order to control our cocktail machine with our phone, we will create an app with MIT app inventor .

Only requirement a gmail acoount. You can upload my app and modify it in the app inventor it is very easy to use but i will advice to check some tutorial before.

To be able to install the app you have to go to your phone setting (in security) allow unknown sources.

Important :
To send value from the bluetooth i used the object "send text" so it will send the number 1 / 2 etc.

You can also use the "send byte number" but it use ASCII so in order to send 1 to the arduino you need to send the value 49 Pay attention to the difference .

Step 7: Conclusion

Here we are just few steps to follow .

The most complicated part would be to create the case that fit your needs mine is a bit bigger than needed but i can stock up some botle .

You can change all the drink i used without changing the code (if you use the same quantity ) , just need to change the picture in the app !

I added Voice recognition in case someone is to "tired" to use the app !

Hope you envoy this instructables please share any idea of improvement for the next version !

    Hello again!
    The project (aia) for MIT app inventor is available? It would be very helpful for me! You can help me? Thank you very much!! desavia@mail.com

    Amazing Thomas!! very good work!

    I will follow your suggestion to work with the app inventor. I will have to study because I never use it. Greetings from Argentina and thanks for sharing your work!
