This week was dedicated to continuing with the manufacturing process. In order to give more stability to the components in the structure, it was decided to add a top horizontal plane with holes to fit the pumps, as it can be seen in the final model, Prototype 7 (Figure 11).

A LED strip was added to the outline of the base to get a more attractive design (Figure 13).

The touch screen is working perfectly as shown in Figure 14. The Arduino code is almost ready. The main function of the code reads the signal of the touch screen. Then, there is a specific function for each drink that opens the pumps for a certain time. The time depends on the specified amount of shots (each shot activates the pump for 5 seconds), and the name of the variable which can be: rhum, tequila, coca-cola, grapefruit juice, lemon juice, or orange juice. During this time. the screen shows a message that says "Preparing your drink" followed by "Ready!" to indicate to the user that  their cocktail is ready. The user can press the "Menu" button to go back to the main page and order another drink.
