The (*)555 Timer IC software has been use in countless of electronic project that requires the use of square wave (Astable). NE555 IC can act as a timer, delayed switch (Monostable), Schmitt trigger and simple memory switch. Here a a selection of Youtube videos that demonstrate the usefulness of 555 IC timer for electronic hobbyist.
The 555 Timer can help any electronic hobbyist and newcomer to build circuits with Astable or Monostable configuration. The application is very easy to use as the user only need to key in their desirable value of when the 555 timer should activates or deactivates; and the software does the calculation for the capacitors and resistors value.
The software is written by Andrew Clarkson, and you can download the software from http://clarkson-uk.com/555-timer/
