i used my midisense live a week ago last night with great success despite the possibility of an even more meaningful logic level from my IR distance sensors if i use a pull up resistor!
the great 20 page booklet from Acroname that came with my IR sensor said "... a pull up resistor is required to get a meaningful logic level." and i did not believe it. Someone used a chalk board to illustrate and explain this pull up resistor in this open collector at the Hacktory and i did not believe it.
but now i am going to roll the drum across the room and add a pull up resistor, cause i can't imagine my logic level getting any more meaningful.
and i'm feeling lucky.
