Hi Folks, wondering if anyone has a way of using a 24 relay board with a particle electron that also has the capacity to log relay status to an SD card. Currently we have a 24 relay board controlled by a particle electron;
The timestamp log of the relays is uploaded via gsm to a google spreadsheet. As a backup ideally we’d like the timestamp log written to an SD card as well. Anyone know of a device that is compatible with this setup and can write to an SD? I saw the adalogger which is perfect for the job but unsure if compatible given pin configuration or is there an overlay shield which could help? I’ve provided see links for info.
Thanks heaps in advance for any ideas!
