This simple alarm timer circuit is made with 4060 which has an integrated oscillator with a good stability with a relatively wide frequency range. In the circuit diagram the oscillator frequency is ...

The circuit was designed to produce a timing scheme that will provide a longer span of time to become activated. LM555 – a highly stable device for generating accurate oscillation or time delays with ...

A running joke we see in the comments by Hackaday readers whenever a project includes an Arduino or Raspberry Pi that seems like overkill is to proclaim that “I could have done it with a 555 timer!” ...

If you need a precise time, you could use a microcontroller. Of course, then all your friends will say “Could have done that with a 555!” But the 555 isn’t magic — it uses a capacitor and a comparator ...

Timed activities such as sports, gaming, and cooking are monitored and alerted with digital timers. A digital timer uses an electronic counter circuit to keep track of timed events or activities based ...
