3. 555 Timer Calculator
This is a calculator designed and dedicated to calculating the resistor and capacitor values for the popular NE555 square wave generator.
This is unlike the other calculators you will find floating around. This calculator generates actual, usable component values; values that are found in your kit. No longer will you be asked to provide a 2546.74856Ω resistor.
This calculator will also allow you to tell it which components to use, based on what you have available. Don't have a 10KΩ resistor, or a 4.7 nF capacitor? Remove it from the list and you'll never be asked to use one.
This is a brute force calculator. Meaning it calculates every possible combination and if it comes within 1% of your desired frequency it will display it as a result. If battery concerns or the speed of the results is of concern, users can opt to have the calculations done via remote server. Your custom component list is still used for this process, but results can be generated in a fraction of the time.
Feedback and feature requests are always welcome. No comment too sour!
