Hi All
Attached is a little circuit I will be workin on this weekend...
On the right side of the circuit is a resistor 'R2: 22-220 ohm' meaning that a resistor value between 22 - 220 ohm needs to be chosen in order to not pass very high a sound level into my speaker. The resistor will be connected to a PWM channel.
The speaker I am using has the following specs: max.0.2W, 8ohm!
Any help in choosing the appropriate value of the resistor will be appreciated!
Thanks!
