IC 555 is a basic timer IC for hobbyist or electronic engineers. This app is used to calculate monostable and astable circuit
Features: 1. Calculate monostable circuit 2. Calculate frequency of astable circuit 3. Calculate component values of monostable and astable circuit. Save component values in CSV file (Excel file)
Features in PRO version only: 1. Selectable preferred value of resistors and capacitors 2. Share CSV file to other apps 3. No limitation 4. No Ad
Note : For those who need support please email to the designated email. Do NOT use either the feedback area to write questions, it is not appropriate and that is not guaranteed that can read them.

I have not had any problems with this app. I only occasionally use it, but would not be happy about erasing it from my phone. I used the app today to make a turn signal flasher for a scooter. I like the app has circuit applications. If you're bored and just want something to do and have some 555 chips there is weeks and possibly months of fun u can get from this app. Thanks

I thought this was going to give me the component values to use for the timing parameters I want. Instead I have to work this app backwards to approximate numerous times until I get somewhere near what I need.

For monostable "pulse" tab, you can find R,C or pulse. For monostable "component value" tab, you can find R,C from the pulse time. If you still have problems using the app, please send us an email peterhohsy@gmail.com

No detailed calculation. Constricted functions. Not fully calculable. You could have provided columns in which R1, R2 C, & % could be substituted to find a value or values. You deserve more star for your concern. I will be watching to add more stars, you have tried. Good luck.
