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.
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.
