Hello! I have designed an incredibly simple circuit to demonstrate how hall effect latches work for my class. But it isn't working
I am using AH3761 hall effect latch switches (http://www.diodes.com/datasheets/AH3761.pdf) along with a cr2032 3.3v battery, a red LED and its accompanying resistor.
(red led 5mm diffused, forward current 25ma, forward voltage 1.95v).
My math is correct (3.3v - 1.95v / .25ma = 52ohm resistor.
the led with resistor lights off of the battery, but hooking up the hall sensor (led with resistor on positive lead, + lead going to OUT lead on hall switch, ground going to ground, and the battery is hooked up to the Vdd input lead on the switch and the ground on the hall switch,) and it won't work.
The switch won't work with any magnets! Am i missing something? Please help! Thank you!!!
