When the 555 IC is
used to produce an ASTABLE circuit - it
will continually pulse until power is
removed. Astable circuits can be used to
flash lights/LEDs
Astable circuits
produce pulses. The circuit most people
use to make a 555 . It is easy to modify
the basic 555 astable circuit to produce
this result:
I was using the "Astable
Flip Flop Circuit" page and setting up
the first example, the "flip flop
flasher". I added a potentiometer
between the power supply
An astable/bistable
circuit with integrated digital
multimeter and 2 oscilloscopes for
demonstration or observation of circuit
operation and methodical
