Hi, I have never done this before, so please bear with me!!!
1) I need to turn an external circuit (about 4 volts) on and off. Is there a circuit diagram that I an refer to for this that shows me a layout?
2) I have a number of inputs - pins that I need to set high or low using internal voltage. I expect that this would be quite simple, connecting a switch between +5v and the pin via a 10k resistor? I just can't find an exact diagram to show me this!! When they turn on, I want them to go high.
Maybe next post I will have something more challenging!!! I doubt it though!
cheers, Bruce
