Use the alligator clip wire combo to clip onto the Circuit Playground Express A1 pad. The other end should clip onto your nail or piece of metal. The nail should be in the soil about 2 inches (5 centimeters).

For the Code portion of this build, you will want the Circuit Playground Express connected via a USB cable connected to a computer capable of running MakeCode. The USB cable will provide the Circuit Playground Express power for this portion of the build.

When your code is done on the next page, unplug the Circuit Playground Express from the USB cable and plug in your battery pack. Be sure your off/on switch on the battery pack is set to on.
