I'm going to start posting my blog's here too. Hope you enjoy.
This is the keyless ignition I made for the Electric motorbike. It uses a PICAXE 08M programmed to read the cards ID number and then decide whether this is a correct card or not.
If the correct card or tag is swiped over the reader (ID-12) the 08m sends a signal to the green LED showing that the bike is turned on. If a card that is not programmed into the 08m is swiped, the red LED flashes for 2 seconds, thus telling us that that card will not turn the bike on.
