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 ...

With a 555 on the BOM, you never know what you’re going to get. With 40 of the versatile timer chips in a build, you might just get something completely unexpected, like this 555-based eight-bit ...

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 ...
