It’s important to have nearly equal high and low times for the signal produced by the timer. (Other oscillator circuits use the NE555, but that will not significantly change the results about ...

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 ...

One-shot circuits are popular choices for the on/off control circuitry. You can interface the programmable one-shot design in Figure 1 with any intelligent system, such as a PC, a µP, or a µC. The ...

It has become a bit of a running joke in the Hackaday community to suggest that a project could or should have been done with a 555 timer ... purpose to which the NE555 devices are pressed.

the NE555. (Video, embedded below.) The circuit is simplicity itself, just an astable of the type that has made a billion beepers and flashing LEDs. It drives two ultrasonic transducers in ...
