IC555 Mono-stable Timer Calculator V2 [22-Dec-2013]

In an actual circuit its advisable to make RV1 value a combination of a series fixed resistor
and a variable resistor if a exact frequency is required.
Consult the 555 datasheet to ensure that it will work at the calculated period.
High Period=
Note: The initial default values for RV1, 1000K [1megOhm] and C1 = 1uF The RV1 value can be changed by using the drop down Select box for RV1.
To adjust the RV1 values, Press and Hold down the Left Mouse key on the Slider button.
