I will be using a optical rotary encoder sensor with my arduino uno.
I am a beginner with using arduino, so I have a question regarding my power source.
For my project I will need to have the power source of 12V 10amp battery (car battery pretty much).
Am I able to connect this straight into my arduino uno, or do I need some type of shield for that high of voltage and amperage?
Any help would be appreciated. Thank you for the help.
