There is many a comment on these here pages along the lines of “Why did you use a microcontroller, when you could just have easily used a 555 timer!” And, yes, we sometimes agree with the sentiment, ...

“You should have used a 555” has become a bit of a meme around these parts lately, and for good reason. There seems to be little that these ubiquitous chips can’t be used for, and in a world where ...

The project makes use of a monostable 555 timer circuit and a relay to drive the load in order to create an aquarium feeding timer. The setup of the circuit is a one shot trigger or timer where the 55 ...

Sure, there have been some pretty creative variations on the standard paper business card, but if you're looking to make a career in electronics engineering, card stock isn't necessarily the best ...

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 ...

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. In the process of making this circuit, we'll make a pcb design for it. This ...
