 ## Description
 
-The project is an automated coffee machine that allows the user to choose exactly how much sugar and coffee they want. The process is simple: you turn on the device with a button, select your desired quantities from the menu, and then press a start button. The system then pours the sugar, coffee, and water in the correct order and mixes them together. The result is a finished iced coffee.

+The code is structured as a state machine, where every action is executed one at a time following the diagram flow. After finishing the coffee, the user can clean the mixer by putting in a new cup and waiting for the machine to pour clean water.
+
+For the part where the user needs to put or get the cup, the code waits while measuring the distance to the cup to see if it is present or not.
+
+User interaction is handled through the buttons and the LCD. The user selects the desired quantity using the buttons, and the LCD provides immediate visual feedback.
+Also the LCD shows the progress of the preparation.
+
+For the display, the LCD uses an I2C converter in order to communicate with the board. The code sends commands to set the cursor position, and then sends the ASCII number of the character in 2 different signals in order to put the letter on the screen.
