Used in a variety of timer, pulse generation, and oscillator applications ... and appreciation for one of the most successful circuits in electronics history. In this design, a classic 555 timer IC ...

This is different than the standard 555 oscillator circuit in that the LED is placed in the capacitor reset line (pin 7). By doing so, overall current is reduced and the high peak LED current does not ...

[fahadshihab], a young tinkerer, shared his circuit design for a simple remote control using 555 ... circuits in order to synchronize them. It would be easy enough to interface this with an ...
