Hey all
I am driving a piezo directly off an 08M2 pin using the sound command and its pretty distorted. Its one of those small encased types you see in alarm keypads etc- about 10mm diameter.
Mounting on the case has not made it better. Tried a couple of other piezos - same issue.
Resistor in line? Its not very loud anyway (depending on what freq you drive it with). I thought a resistor would make it worse.
5v supply. Any ideas? No higher voltage available to boost it.
As a slight sideways question. Anyone got recommendations for decent hook-up wire? I am using old alarm cable multicore stripped down, but its horrible to solder with. The sleeving melts at very low temperature.
