initial draft of cheatcode-safelock
A combination lock sketch inspired by cheatcodes in the GTA franchise. You can set a passcode with the combination of the buttons on your controller.
Currently only supports PS3 controller via USB HOST SHEILD. Support for PS4/XBOX360/XBOXONE is coming, as well as bluetooth support.
I am more of a software engineer than an electrical engineer, hence why this code does not feature a whole lot of interaction with the base board. I hope to get better at it.
This sketch is dependant on: USB_HOST_SHIELD_2.0
