Simple circuit for a Arduino
Budget $10-30 AUD
I would need Simple circuit design that does the following 2 tasks for a 5V arduino pro mini
1. Power the Arduino (5V) from a car Battery (12-16V) including protection circuit.
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
