A-Z of car ignition systems

Try substituting the relay coils for leds in the correct orientation to see what's happening there. The schematic looks ok to me, it may just be something you've done when you've laid it all out.
-
Cheers. I though somehow that when I swapped the orientation of the diodes I might have stuffed up the work you started. If the scheme is correct I'll work on building a board

lol making the threads for the PCB is actually fun...its like a puzzle game.
im not getting a good score yet, but if i keep trying ill win eventually
:D
-
lol. It's awful isn't it. especially when you're making a single sided board.
Single sided boards are more art than anything else. Double sided is a bit of a cop-out really. It's routing everything without using too many jump links on single side that is the real work of circuit design. -
so the arduino arrived today..pretty flashy looking....still got to finish my PCB design....having issues as i dont have the final relay yet to make sure my measurments match
-
Just make sure you breadboard it first. It'd be a pain to get a board made up and have to change it.
fyi I was doing a funky thing with diodes in mine to add extra powered outputs and ended up burning them out on a main road. Instant loss of car power and a panicky moment in traffic.
I really shouldn't have used diodes to do that with, at the moment I have wire links in the same place and it's fine. -
will do @Lokki
i think i got the code wrong somehow...

Looks like you've either not installed the NFC libraries or you've got it slightly wrong, dude.
the pn532 libraries come with 3 or 4 sub folders in the main folder, you have to copy the sub folders into your arduino libraries and disregard the main folder. -
Is there any other NFC reader or a good way to separate the antenna from the board?
I'm thinking it would be pretty neat to have my car start when I rest my hand on the shifter, but obviously the whole board wouldn't fit on there. -

@lokki dodgy usb cable with the aduino
-
Heh, I guess that'd do it too!
I just got my microview units so I'm going to be altering the car starter to incorporate one of those instead of the microduino, the microview has an inbuilt oled display, so I'll be able to do something nifty with that instead of the big string of LEDs across the dash to show mode.
