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

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 ...

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 ...

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 ...

Used in a variety of timer, pulse generation, and oscillator applications, the 555 was designed in 1971 by Hans Camenzind. A favorite for many engineers, the 555 is still in widespread use due to its ...
