Hello and welcome to my Lemonade Machine instructable.

This is a fun project I made for my schoolwork "If This Then That". I made this arduino project because I was to lazy to go to the kitchen to get myself a drink. So if you had the same problem than you are on the right page.

With the lemonade machine you don't have to decide which drink you have to pick because it will pick it for you. And for the people that like a bit of fun, with the timer you will have to make your drink fast and set a record for yourself and friends. I you will enjoy this tutorial and that it will come to good use.

Step 1: Components

What do you need:

- Arduino Uno

- Buzzer

- Survo

- Micro server

- Pushbutton

- LED x 3 (different colors)

- Resistor 220

- Wood glue

- Wood (you need to creat a 3 boxes with 4 short sides and 2 wide sides p.b)

- Drinking tap x3

-Screws x12

-Long male to female jumper wires x 17

-Tin (soldeer tin)

-Soldering iron

-Door hinge x3

-Tube x3

- small paper to write on and color

(In the picture you can also see which tools I used for this project)

Step 2: Getting Started

1. Start by saw your wood to get 12 small pieces (14x7 cm) and 4 wide pieces (14x14). Use 3 of the small pieces to make a hole about 4 cm wide.(check your tap for the correct measure, you will need to fitt the tap in the hole later)
2. Use your wood glue to glue the pieces together to create a box with a hole. So now you will have a open box consisting of 3 (14x7) piece of which two have a hole to put the tube in between, the 4th piece you need to scrub the sides to make it slide in better.
3. Put the tub in between the holes and use super glue or wood glue to glue them
4. You can now close the lid by slidding the other wood piece in
5. Ad the tap at all 3 boxes and you should have it done like the last picture in the slide

Step 3: Testing Arduino With 123D Circuits

Now we will create our aurduino in 123d circuit or thinkercad. First build the circuit as shown in the first image.(see first image) Next set up a servo and a 7 segment display as shown in the rest of the pictures.

Step 4: Setting Up the Code

Now we need to set up the code. So the main loop, loops through all the different function.

So first we have the melody that plays then the arduino waits for a button to be pressed. When the button is pressed the 3 LED's will start flashing one by one. When the button is pressed again the LED that was on is saved and will flash meanwhile the servo will wave (if you made a sign). This will go on for as long as you make this function last. Next the timer starts to count up until you press the button again to end the whole sequence. So the melodie plays again and arduino waits for you to press the button.
