In this video, I'll show you how to combine several components that I've demonstrated in previous videos into a "pincode puzzle" - in which a four-digit code entered on a keypad will be displayed on an LED display. If the code entered matches a preset PIN assigned in the Arduino code, the Arduino will activate/de-activate one of four relays (which, in turn, can lock/release a maglock etc.)
