Thanks in advance! I have a circuit board with a built in "buzzer" but its more a chime. There a two posts, + and -, on the back of the board that pulses with 2 volts when the chime chimes. How could I hook an amplified speaker into this?? I need to make the chime or buzzer MUCH louder. I have a power outlet very near the board figuring that external power would be neccessary THANKS AGAIN!! |
