EXCITING EXCITING!!
I got the servo to work with the rfid (so when I first scan my card the servo opens, and then the next time I scan my card the servo closes). I was able to do this by modifying Arduino’s example code for the servo to work for my own file (added an if else statement inside the if loop that happens when I scan the correct card). And then I decided to add a buzzer whenever the wrong card is scanned so whoever’s trying to break in gets a surprise sound.
Next I’m going to start doing the CAD for the case.
