Another fun I/O device

[petez69]

I've interfaced another RaspberryIO device to the arduino, this time CCTV motion detect. I've built a RaspberryPI up with a relay HAT that receives ModBUS commands from the SYnology NAS. I've got 2 cameras detecting motion which trip input on the arduino. I've also got a 3rd relay on a CRON job that trips every 24 hours to tell me its alive :-)

A little Sunday afternoon project :-)
