Hi all,
Could anyone advise me on a project?
I am using 10 x hall effect allegro A1125 sensors as switches, digital ins to trigger midi note on/offs.
I came across some Unipolar Allegro A1157's, which are (in effect) 2 pin switches, which reduces 3 pin connections to 2 pins.
My question is; how do I connect the 2 sensor pins, which are ground and 3 volts positive, to a digital pin in, on the Teensy. (I am using a teensy LC).
Do I connect the 3v sensor pin to 3v, and the ground pin to a Teensy digital pin, or vice versa?
And, do I need any other components, caps, resistors etc in the circuits?
Thanks in advance,
fil.
