Timer IC 555 Calculator

Calculation of astable and monostable circuit

Features & Capabilities

Timer IC 555 Calculator is a powerful Chrome extension designed for electronics hobbyists and engineers to efficiently calculate circuits based on the popular IC 555 timer. It supports both monostable and astable circuit calculations, providing accurate frequency and component value computations.

Key features include the ability to compute values for monostable circuits, determine the frequency of astable circuits, and generate component values which can be saved in CSV format for easy documentation or sharing. The PRO version unlocks additional benefits such as selecting preferred resistor and capacitor values, unlimited usage without ads, and sharing CSV files with other applications. For user support, direct email contact is recommended rather than feedback comments.
