i need formulas or something telling me how voltage change effects the period on a 555 timer
everywhere i look the websites keep telling me that it is usually disconnected or attached to a capacitor to ground
also is there a free circuit simulator somewhere on the internet i have been using this site
Circuit Simulator Applet
but today i have found out that the maximum frequency on the scope is only 16kHz and i need to measure between 25kHz and 60kHz
i need to select components for a 555 timer to make the output frequency at min 25kHz and at maximum 51kHz
but the period is determined by the control pin
