Hi
I would like to be notified by a light when someone puts something in my mailbox. I would need 2 magnetic sensors (or switches). I was told I can use a 555 timer for this. The objective is when someone opens one of the 2 mailbox doors it triggers and turns on a led. I can see the led from the house. This can only be turned off by a manual reset push button. Battery operated is best. Thanks
