# Scan WiFi networks on button press

## Overview

This app demonstrates how to scan for available WiFi networks. WiFi scan

is triggered by a button press.

On NodeMCU and DevKitC, a button pin is already configured to pin 0,

which is a "Flash" button.

If you have your button on another GPIO pin, go to the configuration,

expert view, and change the pin number:

```

  "my_app": {

    "button_pin": 0

  }

```

Press on a button. You should see WiFi network list appearing on

your console:
