Description
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.
