I have some problems , I' m have compiled the scheme for the syringe, when I touch the quartz serovo drive works by itself. how to make an indicator - a light bulb about the state of a closed door, for example when closed - lit, open - off. Thanks

[@rodrigocml]

Hello, thanks for the tutorial. Is there a way to add more accepted cards?

[@RoboticaDIY]

i have updated my post for 2 card access also. you can add any number of card by doing same steps. please visit

[@rodrigocml]

Thank you!

[@creydox4151]

Hallo the link doesnt work. I wont to add a second Card too. But I dont know how.
