The 555 Astable Circuit

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

The 555 Astable Circuit - More Detail

This is a typical 555 astable circuit that drives an LED.

555 timer

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:

Astable Flip-flops

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
