Topic: Arduino Uno External Power Cable (Read 2967 times) previous topic - next topic


Hi there,

The Arduino Uno in the starter kit has a socket for an external power source, but there's no power cable for it.

Where can I get a cable so that I can power the Arduino in a stand-alone project?

Thank you!


any electronics supply try the robotshop use a 9v dc ac adapter   any arduino supplier should have it I would avoid 12 volt units . Try the RobotShop they will have an adapter with same size mm as the arduino receptacle and same polarity
