  • RFID+Relay+RFID Door Lock Code = RFID PC Switch! 9 days ago

    Hi there!

    Thanks for the comment.

    Have you tried to double check everything? The connections, the wires, the code, the wires that are connected to the computer, etc.

    If you have tried everything, I think you could use a different relay code and just add the MFRC522 code from this project to the one with the other relay code.

    If it still failing, try a project with just the relay, or with just the RFID reader, maybe one those are malfunctioning.

    If both of them are working correctly, try using a different code from a different source.

  • Sound Sensor Activated LEDs with LCD for Sound Level Data! 2 months ago

    Thank you for the reply. The description of the product says

    "The sound sensor module provides an easy way to detect sound and is generally used for detecting sound intensity. This module can be used for security, switch, and monitoring applications. Its accuracy can be easily adjusted for the convenience of usage.

    It uses a microphone which supplies the input to an amplifier, peak detector and buffer. When the sensor detects a sound, it processes an output signal voltage which is sent to a microcontroller then performs necessary processing. "

  • RFID+Relay+RFID Door Lock Code = RFID PC Switch! 2 months ago

    I'm not sure about how many cards can be stored or saved, but, according to this link: https://github.com/martymcguire/ArduinoRFIDDB: "an ATMEGA328 has 512 bytes of EEPROM storage, can store 51 tags".
