  • Sound Sensor Activated LEDs with LCD for Sound Level Data! 4 days 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. "

    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".

    Oh, I used a 12v dc power adapter to power the Arduino. Alternatively, you can use a 9v battery.

    :D
