I was trying to set up an emergency button in my robot, which is powered up by the Ubiquity board. In this scenario, I tried to make a configuration where, when I press the button, the motors stop, and only them - the Raspberry, the board and everything are still powered up.
However, I don’t know how to set up the connections to cut the energy from the motors in order to stop them from running. I’ve tried to see if powering up the 14th pin - below the one you power up the board - would work, but nothing. Does anyone know how to do this?
Thanks in advance!
