I need help with pulse width modulator with constant 12volt output
Hi all hope some one can help with this.
I need to build a circuit that will allow a constant 12volt until its activated, when its activated it needs to pulse the output just like a pulse width modulator, when switch off it must go back to a constant 12volt until its activated again.
The output needs to supply a +12volt rail to drive an array of bulbs.
Ive tried to show more details what I need in a diagram
