The digital inputs and outputs (digital I/O) on the Arduino are what allow you to connect sensors, actuators, and other ICs to the Arduino . Learning how to use the inputs and outputs will allow you to use the Arduino to do some really useful things, such as reading switch inputs, lighting indicators, and controlling relay outputs.

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.
You can connect small servo motors directly to an Arduino to control the shaft position very precisely.

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.
You can easily interface a liquid crystal display (LCD) with an Arduino to provide a user interface.
