Okay this is simple.. I thought...
I'm using a 555 timer as a "Safety Switch".
A microcontroller will be programmed to send power to a 555 timer right after a button is pressed. The 555 timer's output will be connected to a micro relay coil. The coil will need to be energized for about 10 seconds.
Think of it this way:
Once power is applied to a 555 timer, I want an LED to be cut on for 10 seconds, and cut off (NO FLASHING). Once power is taken off, and applied again, this "system" will restart.
I would like a simple circuit to do this..
Thanks!
