I'm sitting here with my Raspberry PI and some other equipment that requires digital signal (high/low, enabled/disabled).
But the Pi only has a GPIO so to get it to work I would need a microchip of some sort (guessing)?
I'm fairly new to all this, but like to play around on my breadboard.
Could anyone point me in the right direction here? I need the PI to control a device that operates with digital high/low signal but also "enabled" / "disabled"
