Cocktail Machine: Smartphone Controlled

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

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

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 tutorials please share any idea of improvement for the next version !
