littleBits w8 latch

I used to have to hold the button down the whole time, which got old fast. This turns that momentary press into a proper on-off toggle, so now I just tap it once and my circuit stays running. Exactly the piece I was missing.

Hooked this between a pressure sensor and my LED strip and now one tap keeps the lights on instead of me holding the button down. Took me a minute to figure out the latch versus momentary thing, but it's exactly the switch my little door alarm needed.
