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 ...

An Arduino Nano controls two relays which in turn can turn the car on, start it, and turn it off. Instead of adding a button for “push to start” he opted for a 13.56MHz RFID module.

To build this DIY buzz wire game, you'd need an Arduino Nano, a 9V battery, two LEDs (red and green), a buzzer, a seven-segment LED display, a shift register for the display, and resistors for the ...

Figure an Arduino most matches the "Other" category. To be specific, it isn't an Arduino brand, it is a DigiSpark, but the trouble isn't with the device itself. The problem is with a buzzer. I got ...

Save for the Arduino Nano, it requires pretty basic electronic components you might already have on hand, including three different colored LEDs (green, orange, and red), a 10k-ohm resistor, and a ...

Other features of the Maker Nano RP2040 small board which measures just 49.53mm x 21.08mm in size include support for the Arduino IDE, CircuitPython and MicroPython.

The power of Espressif’s ESP32-S3 meets Arduino’s unmatched customer experience, documentation and community — all in the compact form factor of the Nano. Provides support for both ...

A cool RFID music table has been created using Arduino, iPod, and RFID tags to make it easy to change albums by simply changing the RFID tag. Each RFID tag has an individual code number relating ...
