I’m considering powering my next Arduino project with a DC power supply. I need to power:
- Arduino UNO, approximately drawing 30 milliamperes (5 volts).
- Oled connected to the Arduino, approximately drawing 30 milliamperes (5 volts).
- Solenoid, approximately drawing up to 2 amperes (12 volts).
In my thinking, I need some sort of a power supply that will give me both 12 and 5 volts and it must be able to provide me with say 3 amperes.
My question to someone who has the knowledge is:
Would it be possible to use a 12 volts 7 amperes DC power supply in conjunction with a switching regulator. That way being able to supply the 12 volts and enough amperes to the solenoid as well as providing the 5 volts and enough amperes to the Arduino?
Your time and knowledge is very much appreciated.
