| - | Proiectul meu constă într-un aparat automat de preparare a cocktailurilor, bazat pe placa Arduino Uno R3 și echipat cu patru pompe controlate prin relee, un LCD keypad shield pentru selectarea rețetelor și un buzzer care semnalizează și întreține atmosfera cu muzică. Scopul meu a fost să automatizez dozarea precisă a ingredientelor pentru a obține consistența băuturilor și să creez o experiență interactivă. Ideea mi-a venit la o petrecere, când încercam să îmi prepar o băutură și dozajul nu îmi ieșea corect, iar atunci m-am gândit că ar fi fost mult mai ușor dacă exista un automat care să facă asta pentru mine. Cred că proiectul este util atât pentru petreceri, cât și pentru baruri de acasă, oferind un mod interactiv și precis de servire a băuturilor. | + | My project consists of an automatic cocktail-making machine, based on the Arduino Uno R3 board and equipped with four pumps controlled via relays, an LCD keypad shield for selecting recipes, and a buzzer that signals and enhances the atmosphere with music. My goal was to automate the precise dosing of ingredients to ensure drink consistency and to create an interactive experience. The idea came to me at a party, when I was trying to make myself a drink and couldn't get the proportions right — that’s when I thought it would be much easier if there were a machine to do it for me. I believe the project is useful both for parties and for home bars, offering an interactive and precise way of serving drinks. |
