This sketch is missing a short description

From Adafruit tutorial on DC motor. --5V from Arduino to breadboard, --to red lead of motor --to 'gate' of diode --to right leg of transistor --center leg of transistor goes to 'gold' side of 330 ohm resistor --orange side of resistor goes to PWM digital pin 3 on Arduino --left side of transistor goes to ground --right side of transistor goes to blue lead on motor https://learn.adafruit.com/adafruit-raspberry-pi-lesson-9-controlling-a-dc-motor
