No pull-up/down resistor ?

Post by adi1133 »

In the schematic i cant seem to find the pull up/down resistor for the button or the hall sensor.
What am I missing ?
edit: nvm the chip probably has some form of internal pull up.
Another question is ... how does the hall effect sensor work ?
I fully understand the sensor part ... Im a bit confused on the output part.
I've read that its like a switch, Q and Vss act like pins on a switch , right ?
I'm working on a similar project but with a PIC .
