Card cloner
Introducere
Scopul proiectului este realizarea unui copiator de carduri, un aparat care permite citirea unui card/cartele prin intermediul unui modul special pentru scrierea si citirea cardurilor si copierea datelor de pe un card pe altul.. Reusirea citirii cardului va fi semnalata de aprinderea unui LED.
Descriere generală
Prin utilizarea Modulului RFID522 putem citi o cartela/card astfel incat se poate realiza “accesul” respectiv. Modulul va fi conectat la o placa Arduino UNO care va citi semnalul si in cazul in care accesul este permis, un LED se va aprinde.

Rezultate Obţinute
S-a reusit citirea, copierea si transferul datelor unui card pe celalalt. Din pacate nu merge si cu cartela de camin caci e pe alta frecventa.
Concluzii
Acest proiect m-a facut sa fiu mai curios despre ce device-uri poti concepe folosind materia predata si in continuare voi face mai mult research pe acest domeniu.
