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.
