How It Works

The adaptor connects a standard 9V battery snap connector to a DC barrel jack plug matching the power input socket of an Arduino board. When the battery is attached, it delivers direct DC voltage to the board's on-board voltage regulator.

Why Build This

Enables portable operation for Arduino projects
Inexpensive and quick DIY build
Eliminates reliance on USB cables for mobile setups

Real-World Application

Portable electronics, field-deployed sensor nodes, and mobile robotics powered by Arduino.

Skills You'll Learn

soldering basics | wire stripping | power connection management | battery power integration

Safety Precautions

Ensure correct polarity when wiring the battery connector to the DC jack to prevent damage to your Arduino board. Avoid short-circuiting the 9V battery terminals, and use insulated wires or heat shrink tubing to cover exposed solder joints.
