Formula
## 555 Timer Monostable Mode ### Formula **T = 1.1 x R x C** A trigger pulse starts timing. The output goes high for time T then returns low. The circuit requires a new trigger for each pulse.
Esempio Risolto
R = 100k, C = 10 uF.
- 01T = 1.1 x 100000 x 0.00001
- 02T = 1.1 seconds
- 03T = 1100 ms

What triggers the monostable?
A negative-going pulse on pin 2 (trigger) that drops below 1/3 Vcc starts the timing cycle.
Can I retrigger during the pulse?
Standard 555 is not retriggerable. The pulse runs its full duration regardless of new triggers.
How do I make longer delays?
Increase R or C. For very long delays (minutes) use large capacitors or cascade two timers.
