Hi,

Can I connect 5V to the D21G Proto input digital pin without risk ?

And will it be HIGH when reading this pin with digitalRead ?

Regards.

Hi,

Thanks for the information, as I understand, I have to add a pull up resistor or is it optional ?

Regards.

if you have a 0/5V digital signal going into the PROTO, no need for pull-up resistors. only when you want to output 5V you need the pull-up resistor
