Plug the RFID module into the breadboard with enough space around it. Connect the VCC pin to the Arduino's 3.3V (not 5V), and ...

However, the datasheet specifies I2C interface level to a maximum ... Shown below is the basic hardware setup diagram. Here, Arduino’s (Uno R3) A4 (SDA) and A5 (SCK/SCL) pins are used for the I2C ...

In addition to its stackability and low-voltage powering capabilities, the EasyNixie module also offers robust Arduino support. An Arduino library is available to interface with the modules ...

Finally, [James] designed and 3D printed a neat enclosure for the Arduino-USB interface, which makes it look almost as sleek as the original CommsLink module. Perhaps with a bit of further ...
