Anyone who has designed circuits using the 555 timer chip will, at some time have wished that it could be programmed for longer timing periods. Anyone who has designed circuits using the 555 timer ...

The 555 timer IC has been around now for quite some time and the list of potential uses for this device appears to be endless. This article contains a few examples of circuits that you might ...

Sometimes the best inspiration is limitation. The 555 timer does “one thing” — compares a voltage to a couple thresholds and outputs a signal accordingly. It’s two comparators, a voltage ladder, and a ...
