Arduino Tutorial #1 - Digital Inputs and Outputs - Button
The pin D3 of the Arduino is connected to the resistor. Just like when using an LED, this limits the current flowing into the transistor through the base. There is a diode connected across the connections of the motor. Diodes only allow electricity to flow in one direction (the direction of their arrow).

A Solenoid Tutorial. The bypass diode. The schematic shows a bypass diode, D1. When the solenoid is on or idle this diode will not conduct. You do need to connect your Arduino ground to the ground shown on the circuit and also place a 10k resistor from the gate to ground to make sure it stays off unless the arduino pushes it on. FET
ldr High-Power Control: Arduino + N-Channel MOSFET
Arduino (I've used an Arduino Micro but any Arduino will suffice) 12V (or equivalent The diode I have used is a 1N5819 1A Schottky Barrier Rectifier which is a type of diode that allows both very fast switching and low forward voltage drop which is perfect for speed control using PWM.
