#GPIO examples

Following is a simple example on how to wire a led or a push-button.

We used just two lines in this example but more lines are available and every one is
configurable either in input or output mode: [see the Aria G25 pinout](/pinout_aria).

To learn how to drive the led or read the push-button state visit this article: @article='gpio'.

All the lines are at 3.3 Volt. Do not connect any 5 Volt logic level signals to avoid damages.
