The conventional 8 pin DIP package is the most common, but a T metal can type is also available. Supply voltage requirements range from 3 to 18 volts, making the 555 one of the most versatile ...

[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 timers. Using a 555 calculator, he designed a clock circuit that would run at 11.99 Hz. Two transis… ...

Let’s Look at the Schematic In a PWM circuit, the 555 timer will output a logic signal “high” and “low” depending on a ratio derived by the value of a few components connected.

Whenever I use the 555 timer, it seems that the output polarity is invariably incorrect, and the way the 555 functions, it normally cannot generate a duty cycle of less than 50% — 90% yes, 10% NO!

[Kenneth Finnegan] took the focus of a great design and redirected it to solve his own problem. What results is this lead acid battery charger based on the 555 timer. It’s not a top-of-the-li… ...
