Description: This Arduino project integrates an NFC reader, a servo motor, and LEDs to create a simple access control system. The system operates as follows: When a specific NFC card is detected, the ...

The button states could easily be read by using an Arduino’s analog input. A Pro Mini model was chosen for its small size as it could be housed in the radio compartment of the dash.

The interface offers some additional features. If you hold down the left button on power-up, it will display all the .SCR files on the SD card. (.SCR files are screen dumps from the ZX Spectrum) .SNA ...

It’s worth noting that the actual USB interface is being done with a stand-alone controller, so the Arduino here is being used purely to drive the lighting effects.

The OONTZ uses a 3D printed case, a 16 button keypad, an Arduino Leonardo, a monochrome driver, and a few potentiometers. It's actually a pretty simple thing to build yourself provided you can the ...
