That’s why the software serial trick is used here.) /* * PN532 NFC RFID Module (v3) * Quick Test Code v2 * Based on an example code from PN532 Arduino Library * Tailored for HSUART & Arduino Uno * T.K ...

[Pierre] recently bought his first car and decided to make his own RFID electric starter for it! An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off.

An Arduino, a spent roll of toilet paper, magnet wire, and a few passive components are what’s needed to build this RFID spoofer. It’s quick, dirty, and best of all, simple. However ...

The flexibility of the Arduino platform means that the RFID music table can be customized to suit a wide range of needs and preferences. For example, additional features such as volume control ...

I just received my RC522 RFID reader and made this simple Arduino access control system that uses the reader, a buzzer for the alarm and a relay shield for the security system. The relay can be used ...

Pulse-width modulation, for example, is important for driving ... We made a kegerator that uses an Arduino Duemilanove with an RFID reader for access control, [and] a solenoid [a device that ...

When you think of Arduino projects, your mind likely goes straight to RFID door locks, weather sensors, or automated plant watering systems. While these are undeniably pretty cool projects ...
