High signal from pic to pic w/(2) pwr supplies?
January 29, 2010
So here we go:
Walter has (2) 7.2v packs, one for data and one for servos. Each has a switch and can be turned on idependantly (manually). During the "start-up" routine, I need the main picaxe to know if and when the servos have been turned on. It would be like this:
I turn on the main brain. The LCD turns on and displays a message to tell you to "turn the servos on, please" --I need the main brain to know when you have turned them on.
I need to send a simple data-level signal from a 5 volt source to a pic when that 5v source is running off one volt regulator and battery and the pic is running off of a different volt regulator and battery. Should I do this with a transistor? Diodes somewhere?
