This is going to be kind of a messy thread, as it’s my first “build log”, first time messing with Arduino, and therefore keeps evolving.
I can’t use the xAC with my NExT, as the xAConly works with EM4200 formatted chips, and I switched mine to Wiegand for work.
I’m using an arduino Nano, a PN532 NFC reader, and a dual channel relay.
I’ve got everything wired and coded to run off the car’s power, so I don’t need a external power source, and the dual channel relay allows me to both lock and unlock the car with one reader and microcontroller.
I’ve got a couple pictures of my attaching it to my vehicle that I’ll upload when I finish wiring it all in (Should be today/tomorrow).
I have concerns with draining the car’s battery, so I’ve ordered a capacitave touch sensor I plan on adding in the next week or so in order to take advantage of the sleep mode function of the arduino without having to add an extra step in the unlock proccess. I’ll update the thread as I figure out how ti make that work through the sideview mirror’s plastic I’ve opted to mount the reader inside of.
