555 Timer Calculator
Hi everyone, I was looking around on the internet a while ago for a calculator for 555 timer circuits and couldn't find one that worked very well.
Then I set about making my own in a Excel spreadsheet to calculate the frequency and duty cycle for me. I have decided to share it with everyone to help others.
It is quite simple. Enter your vaules into the yellow boxes and get your frequency and/or duty cycle from the blue boxes.
