IC555 Astable Timer Calculator V2 Type1 [21-Dec-2013]

Due to tolerances in the resistors and capacitor used in an actual circuit its advisable
to make RV1 and RV2 values a combination of a series fixed resistor and a variable resistor if a exact frequency is required.
Duty Hi= Frequency= Period=
Note: The initial default values for RV1, RV2 = 1000K [1megOhm] and C1 = 1uF These RV values can be changed by using the drop down Select boxes for RV1 and RV2.
To adjust the RV values, Press and Hold down the Left Mouse key on the Slider button.
