Timer IC 555 - Calculate Timer Values Easily

"Timer IC 555" is an Android app designed for calculating and reverse engineering the values of resistors and capacitors for the 555 timer IC. It allows users to limit component values to E3/E6/E12/E24 series, calculate frequency and duty cycle based on selected resistor and capacitor values, and generate a waveform output. The app also supports reverse calculations, providing a list of recommended components based on user-defined frequency and duty cycle, optimizing the design process for the astable mode of operation.
