Frequently asked questions
Can I power an Arduino Uno with a 9V battery using this cable?
Yes. The Arduino Uno barrel jack accepts a center-positive input in the recommended 7V to 12V range, and a 9V battery falls within it. Battery capacity limits how long the project runs.
Which wire carries positive and which carries negative?
The red wire is positive and the black wire is negative. The male plug has positive at its center pin and negative on the outer sleeve.
