Overview: This project demonstrates a comprehensive Arduino-based RFID door lock system designed for secure access control. Utilizing the MFRC522 RFID reader module, a servo motor for door mechanism ...

This embedded systems project plays the Godfather theme using a piezo buzzer and 16x2 I2C LCD display, driven by an Arduino Uno. All tones are generated through direct I/O control using AVR assembly, ...

It is equipped with 32 Inputs (16 x digital 4-30V, 8 x analog 0-10V, 4 x analog 0-5V, 4 x analog 4-20mA) and 20 Outputs (8 x relay 250V/5A, 2 x open-collector 30V/1A, 8 x analog 0-10V) and offers ...

The Arduino Sensor Kit comes as a standalone kit for only €23.00 or $23.00, or can be purchased with the Arduino UNO Rev3 board as a great value bundle for €38.70 or $38.70.

After uploading the code the Piezo will start making short beeps. On bright light the Piezo will only beep and on dark light it will be short. Some ideas for this experiment: Alarm for Lights in the ...

Analog references are common to microcontrollers that have ADCs. Even if you’re not working with an Arduino, read through the article and use what you learn with your uC of choice.
