Hello,
So just need some advice. I'm using an RFID and an arduino as a switch to power up my motorbike so i don't have to use keys.
So scan the RFID tag and it switches on the supply power to the bike scan again an it switches it off, simple.
So the power supply for the bike is 12 volt. I've got a step down for the Arduino power I was thinking of using a voltage level shifter as its quite reliable way of using two voltages.
what do you guys think?
