Assembly

If you want to use an Adafruit box (or any other cardboard box), there are modifications to make your circuit fit better.

First, place the circuit in the center of the box. You can tape it down to temporarily keep it in place.

 

Make sure the photo light sensor is not blocked by wires. Move wires around if you need to.

Next, cut a small rectangle into the side to fit the USB cable. Be careful while cutting

Finally, pull the wire through the hole you cut and connect it to the Metro.
