#178059 - Piezo? Responding to: ???'s previous message |
Some cheap magnetic buzzers are lousy in terms of linearity, but even often show hysteresis and threshold phenomena. You cannot expect too much from them, often you will be happy if they give a tone at all.
A piezo might be the better choice. The volume can be set by the duty cycle: http://hades.mech.northwestern.edu/index.php...with_a_PIC Kai Klaas |
