Triggering a 555 with another

[abuhafss]

Can anybody tell me if the output of a monostable 555 timer circuit can be used to trigger another similar timer circuit. I have shown my idea with a red line in the attached schematic. If it needs to be improved/modify, please guide me.

Thanks

Hi,

You probably need to 'edge trigger' the second 555

See these sites for details
