Hello,
I know this topic has been discussed many times. But after spending hours searching on the web I just couldn't find a definite answer to my problem.
So I would like to continuesly power an arduino (or ATmega328) in my car to monitor 12V signals.
Here is the schematic:
1. First off all, would this work? I know software better than hardware
2. And second, What would be the safest way to power the arduino whilst keeping the power consumption as low as possible.
2a. Should I just take a car usb car charger? (how do I know it's a good and safe one, design and componentwise?)
2b. Should I create something myself? I found these regulators which seem suited for this; https://www.infineon.com/dgdl/Intro...4.pdf?fileId=5546d46146d18cb40147440c4569288d
3. Power consumption is apparently much lower on 3.3V compared to 5V on the arduino. As the Arduino will always be on, I don't want the battery to drain in 2 weeks. How could I power this with 3.3V?
Any help would be appreciated
