I am in need of a 555 timer that when I apply current to it, it will wait for 1min 30 sec or up to 30 min. The out put after the time needs to power a light and a relay. This is just one part of a big circuit that I built.
I Just resently learned how to use the 555 in astable to have a light flash to the designated hrz. I want this to turn on after a min or two. Could you provide a circuit and the math to determin the R's and C's for the 555 delay circuit. I am new to the electronic world so simplicity is key.
Thanks
