555 circuits using the 555 Timer as an Astable Oscillator
https://www.electronics-tutorials.ws/waveforms/555-circuits-part-1.html
The amount of time that the 555’s output is HIGH is called the “MARK”, and the amount of time when the 555’s output is LOW is called the “SPACE”. So by varying the potentiometer between point “A” (lowest) and point …
555 Timer Tutorial - The Monostable Multivibrator
https://www.electronics-tutorials.ws/waveforms/555_timer.html
By taking the trigger input (pin 2) “LOW”, switch in set position, changes the output state into the “HIGH” state and by taking the reset input (pin 4) “LOW”, switch in reset position, changes the output into the “LOW” state. This 555 timer circuit will remain in either state indefinitely and is therefore bistable.
