My project is about house lock system using 2 arduino system. 1 is bluetooth lock system and another is fingerprint lock system. I have done my programming and system. For my electrical technology engineering course I need create my own ac to dc power supply and solar power system so supply voltage to both arduino. I have done my power supply with dual regulated 12V output and done create my own solar power system. The problem is I want my 12V power supply to supply voltage first and as backup I need solar power but I dont know how to make 12V power supply to supply voltage first and happen blackout then solar power system supply voltage to arduinos as backup. And another thing I dont know how to simulate my timer circuit. I want to make sure my timer circuit is working.
