Hi all,
I'm making a kitchen countdown timer ( my first pic project ) for the wife,
who is half deaf and needs a low to mid range frequancy alarm with some UMPH.
Q1. What's the best way to couple a pic output pin to a 20 watt amp?
Q2. Will the amp try to draw too much current from the pin?
Q3. Should I use a transistor switch ( or pair ) to drive the amp?
Q4. Would a line driver be better than an amp?
I need to keep the internal temperature down as low as posible as it's
going in the kitchen.
Thanks for any help.
