Got this schematic consisting of 2 LM 555. 1 relay which is named Power On Delay Circuit with Flashing/Solid Indicator LED. I want to build a switch which will close my garage door itself after a certain time, like three minutes or more, should I forget to close it.
I would be gratgeful for help on the values of R1's and C1's which are not given. I would also be grateful for advice on other similar schematics for this usage.
