i have been breadboarding like crazy and making a lot of discoveries.

if i am making a simple 555 based synth circuit, how do you make a lower frequency? i tried higher resistors, which i had in stock, a 51k and a 47k...this seemed to make somewhat of a difference, but it also seemed to crash more.

advice?

i'll check these things out...thanks!

is there a formula (in layman's terms) for capacitance and frequency?  higher capacitance=lower frequency?
