555 Basic Monostable Circuit
Basic monostable oscilator circuit can be deginhed by fallowing circuit schema.
Circuit trigger in from pin number 2 and output from pin 3.
The period can be calculated T= R1 x C1
T is, time in seconds
R is, resistence in Ohms
C is, capacitanse in Farads
A negative trigger pulse at Pin 2 turns off a transistor that otherwise shorts C1 to ground, the output then goes high as C1 charges through R1. When the Vharge on C1 is 2/3 Vcc the 555 Discharges C1 to Ground. The output then goes low
