Here is a 1Hz pulse/frequency generator using the popular timer IC 555 which is wired as an Astable Multivibrator. The output pulses can be indicated visually by the LED. An Astable Multivibrator, ...

BNC (San Rafael, CA) has introduced a comprehensive LabView 6.0 driver for the Model 555 digital-delay pulse generator. The driver has been endorsed by the National Instruments Software Engineering ...

The pulse generator is instead built around an STM8 microcontroller; an unusual choice in this era, to be sure. [WilkoL] specified the part for its incredibly low cost, and highly capable timer ...

A free-running generator built on the standard configuration of the 555 timer can't provide a duty cycle of exactly 50%. That's a well-known fact. Fortunately, there are several ...
