Controlling a motor with an Arduino is relatively easy. In addition to simply spinning the motor, you can control the position of the motor shaft if the motor has a rotary encoder.

Infrared (IR) sensors are normally used to measure distances, but they can also be used to detect objects. By connecting a couple of IR sensors to an Arduino, you can make an intruder alarm.

Monitoring the output of a light-dependent resistor, or photoresistor, allows the Arduino to know how light or dark it is. When the light falls below a certain level, the Arduino turns on a couple of LEDs.
