This is the hardware set-up at home,
Raspberry Pi GPIO -> Logic Level Converter -> Arduino -> Multiple Relays
I am running Raspbian and NodeJS on the Pi while the Arduino is loaded with StandardFirmata.
I connect NodeJS to the Arduino with the
johnny-five package and it works well after it's started. But after extended periods, a few hours? The Arduino stops responding. Whatever command that I send to the Arduino won't be acted on. It's as though as the Arduino hung.
Both the Raspberry Pi and Arduino are being powered indenpendently with a 1A Nokia USB Adapter.
Does anyone know why this is happening?
