This project implements an RFID-based access control system using an Arduino board, an MFRC522 RFID reader, an I2C LCD display, an RTC (Real-Time Clock) module, and indicator LEDs with a buzzer. It ...

The use of Radio Frequency IDentification (RFID) technologies is growing. Many different applications are implemented in various sectors, and used for very different purposes. RFID enables wireless ...

This code uses an Arduino board, an RFID reader (MFRC522), and several components (LEDs, a relay, and an input switch) to control access to a certain area or device. The code reads the unique ID of an ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

The SoundPuddle project drives thousands of LEDs based on audio input. The team is working on a replacing the controller for this wire-filled setup with something more robust. They took the mess seen ...

An automatic toll gate system using Arduino revolutionises traditional toll collection by eliminating manual intervention. The “automatic toll gate system project” demonstrates how simple sensors and ...

For the last few years, [Lt_Lemming] was the president of Brisbane’s hackerspace. Until several months ago, access to the local was done using 125KHz RFID tags and an Arduino board with a prototyping ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...
