Obiectivul acestui proiect consta în modificarea cooling pad pentru laptop, cu niste functionalitati adresate cu control mai mare pentru user.

Ideea a pornit de la imbunatatirea unui cooler mai vechi pe care l aveam prin casa nefolosit. Ma deranja faptul ca avea un singur nivel de racire, nu tocmai ideal daca vrei sa fii si econom. De asemenea m am gandit ca pe langa un control mai mare pentru racirea laptopului ar fi bine sa existe perspectiva mai de ansamblu in acest proces. De aici si ideea unui buzzer pentru alegerea modului ales, cat si niste leduri pentru aceeasi utilizare. Un LCD va fi existent pentru monitorizarea temperaturii inregistrate.

Interacțiunea cu sistemul este realizată prin intermediul unui display, care afișează instrucțiuni și opțiunile disponibile ale utilizatorului. Acesta poate introduce durata dorită a programului, după care urmează etapa de plată, unde se va folosi de cardul de fidelitate. Dacă plata este realizată cu succes, programul de spălare începe și periile rotative sunt puse în funcțiune de un stepper motor.

Îmi propun să încorporez în proiectul meu întreruperi, timere și trei protocoale de comunicație: SPI pentru modulul RFID, I2C pentru display și PWM pentru stepper motor.
