8-Pin DIP Timer IC
The NE555 monolithic timing circuit is a highly stable controller capable of producing accurate time delays or oscillation. In the time delay mode of operation, the time is precisely controlled by one external resistor and capacitor. For a stable operation as an oscillator, the free running frequency and the duty cycle are both accurately controlled with two external resistors and one capacitor. The circuit may be triggered and reset on falling waveforms, and the output structure can source or sink up to 200mA.

    Overall: 5 out of 5

    The NE555 is truly a universal device for timing or pulse generation. I needed a 4 second pulse delay, for automatic CNC probing, and used the 555. I coupled it with to a solid state relay and created an isolated output pulse delay. Although the 555 is called a timer, it is actually a voltage comparator with a digital output. Since this device is so popular, the web has numerous tutorials on its use. Every experimenter should have a couple of these, ready for the next timing project.
