Using piezo speaker means you can connecting to the port pin directly with some resistor in series with it? I know I am ignorant here. Learning is the cure for such ignorance. Have you heard of GOOGLE? I'd suggest using GOOGLE to find a few references for you, and, perhaps an actual device's datasheet. Likewise, you might search for a typical loudspeaker as might be used in a radio. Look for a datasheet. That will tell you some things you will need to know. RE |
