The Arduino should keep Power for about 5 seconds after the Battery power is switched off

2. Take a 12-16 V square wave and reduce it to a 5V Square wave via a opto coupler so it can be used with a digital input

I don't need a PCB Layout

Compétences : Arduino, Electronique, Mise en Page PCB, Microcontrôleur, Génie Électrique
