Abstract
In various embodiments, an electronic lock includes a locking mechanism to selectively transition between locked and unlocked states. A controller and capacitive touch sensor to detect and distinguish between short touch inputs having a touch duration less than a time threshold and long touch inputs having a touch duration greater than a time threshold. If the detected series or pattern of short and long touch interactions matches a stored series of touch interactions defining an unlock code, the locking mechanism transitions from the locked state to the unlocked state.
