Timers, Oscillators & Digital
Every timers, oscillators & digital calculator on CalcEngines — unit converters, derived indices and interpretive tools, each with its formula, a worked example and the reference intervals it is judged against.
3 calculators in this section
- 555 Timer Astable CalculatorFrequency, period, high and low times and duty cycle for a 555 in astable mode — or work backwards from the frequency and duty you want to R1, R2 and the nearest E12 or E24 parts.
- 555 Timer Monostable (One-Shot) CalculatorPulse width of a 555 one-shot from R and C — or the resistor or capacitor you need for the pulse width you want, rounded to a real E12 or E24 value, with the datasheet's trigger rules.
- PWM Duty Cycle and Average Voltage CalculatorOn and off times, average voltage, RMS voltage and average power from a PWM frequency and duty cycle — plus the microcontroller timer view: what frequency and duty-cycle step your clock, prescaler and resolution actually give.
