Find out the value of the resistor and the capacitor in 555 timer integrated circuits with user-defined voltages. Includes visual electronic representations and works with both monostable and stable circuits. There's no option to save the result other than manually copying them.
It's a calculator that has 3 astable modes and monostable mode. The software can be downloaded and used for free. You can also tweak various aspects of the cycles.
-3 astable modes
-monostable (one-shot) mode
-duty cycle indicator
-can tweak R & C values
