I have a device that has some type of IC in it, this is unknown for the moment. I can power this IC up with usb power but I need to use a pin from my atmega328 portd. I'm not sure what the issue is but guessing not a high enough voltage or not enough power from the pin. I tried to bring two pins hi and tie them together with no luck. I also added a cap with no success. I'm not sure there is anything that can be done without adding additional components. The reason I need to use a pin is that I also need this wire switchable. In one application I need to pulse the wire and the other supply an IC. Any ideas?
