Breadboard Layout

When you put together the breadboard, there are two things to look out for.

Firstly, make sure that the transistor is the right way around. The flat side of the transistor should be on the right-hand side of the breadboard.

Secondly the striped end of the diode should be towards the +5V power line - see the image below!

The motor that comes with Adafruit Arduino kits does not draw more than 250mA but if you have a different motor, it could easily draw 1000mA, more than a USB port can handle! If you aren't sure of a motor's current draw, power the Arduino from a wall adapter, not just USB

The motor can be connected either way around.
