I am building a circuit to operate a Linear Actuator to open and close a lid.
The open and close times are the same.
The standard monostable circuit works.
There is one switch to tell if the lid is open or closed, it shows 12v+ when open and is grounded when closed.
I have built one timer unit. It works to specs.
I was wondering, since the timers will be the same, would it be possible to use the same components for both timers.
Pins 2 and 3 would use different triggers and the outputs would go to different places as well.
I would use jumpers between the two 555 Chips.
Basically my thought would be to connect all pins but 2 and 3 in parallel with each other.
Would this fly, or am I missing something.
It would be impossible (I trust) to trigger both timers at the same time.

The discharge output is low before and after the monostable pulse, so the outputs would remain low unless you triggered both 555 timers simultaneously.
