Hot of the press and now on publication worldwide, the April 2013 edition of Elektor magazine contains an interesting project inspired by the smartphone: the pattern lock. This is a lock where you slide your finger over the screen following a specific pattern to unlock the phone. Our pattern lock is implemented without a touch screen and without fancy graphics programming. We build one from blue LEDs, a tiny microcontroller and the odd bit of capacitive touch technology. Check it out and add this cool gadget to your front door or gate. Your house will be the coolest on the block and all the burglars will drop by to admire your lock and give it a try.
