A stopwatch is a timer that is used to measure an event anywhere from milliseconds to several hours. We can start and stop the count of the stopwatch at any instant and it can also be reset to zero to ...

This simple circuit automatically activates or deactivates an electronic device at the time of alarm preset in a clock. When the alarm rings, the tone burst generated at the terminal of the buzzer ...

H The analogue brother of this IC is our old friend, the 555. The digital version here, the LS 7210, is less well-known. It can be used to set delay times between approximately 11 ps and 42 minutes.

When a 555 timer is operating in Astable mode, we obtain a pulse on the output pin whose ON time (Time high) and OFF time (Time low) can be controlled. This controlling can be done by selecting the ...
