Hola gente de los proyectos de hive , les quiero contar lo que estuve haciendo esta semana que paso. Estuve metido en un proyecto que me encantó: ¡hice un sistema que lee llaves RFID y reproduce sonidos distintos según la llave que se use, todo con Arduino 🎯. Ideal para talleres, clubes o cualquier espacio que quiera sumar algo de tecnología y diversión 🎶🔍 Además sonaba bastante copado y tenia regulador de volumen. >Hello people from the hive projects, I want to tell you what I was doing this past week. I was involved in a project that I loved: I made a system that reads RFID keys and plays different sounds depending on the key used, all with Arduino 🎯. Ideal for workshops, clubs or any space that wants to add some technology and fun 🎶🔍 Plus it sounded pretty cool and had a volume regulator.  🧩 ¿Qué usé? Arduino UNO (aunque podés usar cualquiera) Lector RFID RC522 Varias llaves RFID tipo llavero 🔑 Módulo DFPlayer Mini MP3 📀 Tarjeta microSD con sonidos precargados Parlante de 4 ohms (¡sonó genial!) Una fuente de 5V con buena corriente 💪 >🧩 What did I use? Arduino UNO (although you can use any) RC522 RFID Reader Various RFID keychain keys 🔑 DFPlayer Mini MP3 Module 📀 microSD card with preloaded sounds 4 ohm speaker (sounded great!) A 5V source with good current 💪 ⚙️ ¿Cómo funciona? Cada vez que paso una llave por el lector RFID, Arduino identifica su UID y activa un sonido diferente. Uno para cada persona o categoría. Es como un sistema de acceso… ¡pero con estilo! 😎🎶 🔌 Conexiones clave: El RFID va conectado por SPI al Arduino El DFPlayer se conecta por puerto serie (TX/RX) y se alimenta con 5V El parlante de 4 ohms directo al DFPlayer ¡Y no te olvides de las resistencias para los datos del lector! 💡 ¿Qué aprendí? Cómo usar múltiples tecnologías juntas (lectura de RFID + reproducción de audio) La importancia de alimentar bien el sistema, sobre todo el DFPlayer Que un parlante simple de 4 ohms puede sonar muy bien si lo usás bien 🔥 🚀 Aplicaciones posibles: Posibles aplicaciones en el ambito escolar o academico. Juegos tipo escape room 🕵️♂️ Sistemas de bienvenida personalizados Alarmas o notificaciones sonoras al pasar tarjetas Estoy pensando agregarle más cosas: luces LED, servo que se destrabe, o incluso control por Bluetooth 👀 >⚙️ How does it work? Every time I pass a key through the RFID reader, the Arduino identifies its UID and activates a different sound. One for each person or category. It's like an access system... but with style! 😎🎶 🔌 Key Connections: The RFID is connected by SPI to the Arduino The DFPlayer is connected via serial port (TX/RX) and is powered by 5V The 4 ohm speaker direct to the DFPlayer And don't forget the resistors for the reader data! 💡 What did I learn? How to use multiple technologies together (RFID reading + audio playback) The importance of feeding the system well, especially the DFPlayer That a simple 4 ohm speaker can sound very good if you use it well 🔥 🚀 Possible applications: Possible applications in the school or academic field. Escape room type games 🕵️♂️ Personalized welcome systems Alarms or audible notifications when passing cards I'm thinking about adding more things: LED lights, unlocking servo, or even Bluetooth control 👀  Este fue un proyecto que me gusto mucho y lo hice con 5 alumnos que tenia a cargo , dio muy buenos resultados y cada vez que leia una tarjeta ademas de abrir una cerradura , tambien sonaba el ruidito de un animal distinto , espero les guste mi post, un saludo a todos amigos de hive!👀👀👀👀 >This was a project that I really liked and I did it with 5 students that I was in charge of, it gave very good results and every time I read a card in addition to opening a lock, the noise of a different animal also sounded, I hope you like my post, greetings to all hive friends!👀👀👀👀
