A tiny clock that integrates air quality monitoring, a timer, and an alarm sounds cool, right? Let's get into the article and ...

You can use a microcontroller to build a clock. After all, a clock is just something that counts the passage of time. The only problem is that microcontrollers can’t track time very accurately. They ...

Figure 1 This classic 555-based timer is valid only for duty cycles greater than 50%. Figure 2 The simple addition of a bypass diode makes this timer circuit valid for low duty cycles. Diode forward ...

As the name suggests the RaceBox MINI has been specifically designed to provide the most accurate drag metre and lap timer available offering “unparalleled functionality” say its creators. The RaceBox ...

The 555 timer in bistable mode is also known as a flip-flop circuit. A flip-flop circuit alternates between two stable states, in this case the output of electrical current from the output pin. Unlike ...

This article is part of the 2022 April 1st series in the Humor topic within our Series Library. The ubiquitous 1971 digital miracle—the 555 Timer—is important, replete with 25 transistors, 15 ...
