Wiring

The wiring from the USB-UART bridge and the RFID reader

Physical UI config

The JSON config for the physical UI allows you to set-up initial transition defaults e.g.

Below you can see the "power" RGBLED has default transition options set. This means all transitions will happen over 750ms.

initialTransition is used to set-up the RGBLED when it's initialised and before any messages to change it's state are received. In this case, the LED will be transitions to the colour [200, 200, 200] over 5 seconds backwards and forwards repeatedly (yoyo).

...

Espruino javascript code to poll for serial number of RFID card. Since the reader communicates over UART, should work with other controllers that have UART, such as the Raspberry Pi.

Works with MFRC500-based RFID Reader/Writer - 13.56Mhz
