What Timer IC 555 actually does (from store listing)
The 555 is an industrial standard timer IC, this app calculates about it.
<b>FEATURES</b>
- Can limit the values of resistors/capacitor to E3/E6/E12/E24 series.
- Simple waveform which will be output.
- Calculating the frequency and duty cycle from resistors/capacitor.
- Reverse calculating the values of resistors/capacitor from frequency and duty cycle. And list up recommended parts.
- Supported operation is only Astable.
