littleBits Latch
This product is no longer available.
Use the latch to turn any momentary input like a button or a trigger Bit into an on-off switch like a toggle!
HOW IT WORKS
If you place a button in front of the latch pressing the button once will turn it ON and pressing it again will turn it OFF again. Or for even more fun place a sound trigger in front of the latch and a light after it...then just snap your fingers!
