In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use ...

Save guides, add subjects and pick up where you left off with your BBC account. The 555 timer is a versatile integrated circuit (IC) that can control timing in electronic circuits. It's one of the ...

In this project, I'll make a small circuit capable of controlling a servo, it is a servo tester made out of a 555 timer IC.

The circuit was designed to formulate a timer that can provide an alert method with the use of a buzzer while the presence of the optocoupler will make it possible to drive an external circuit. 4060 – ...

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 ...

Comprising a microprocessor, an LCD, a 32.768-kHz crystal, and little else, the basic countdown-timer circuit in Figure 1 operates from a commonly available CR2032 lithium-coin-cell battery. Based on ...

Signetics released the venerable NE555 timer in 1971. It has been used in thousands of designs and has been the subject of at least that many articles (see “The 555: Best IC Ever Or Obsolete ...
