Hello everyone,
I have a foot switch. I want to connect foot switch with stm32 mcu. So Im wondering about, can I use foot switch with 12Vdc or 5Vdc?
Thank you for all..

Short answer is yes. But you need to config pin, to use as input, on STM32 with either a pullup
or pulldown, and switch connected to pin to ground or pin to Vdd respectively. And debouce the
switch in code.

Also note if STM32 is running off 5V then pullup to Vdd as shown, for case SW1. or if its 3.3
then switch to Vdd of 3.3.



Regards, Dana.
