Connect No Encryption
This example shows you how to connect to an open (not encrypted) 802.11b/g network with one of the boards that support this library. Your Arduino Software (IDE) serial monitor will provide information about the connection once it has connected.
Hardware Required
Circuit
The WiFi module is integrated on your board and you don't need any special circuitry to get this tutorial to work.
Arduino MKR WiFi 1010
Arduino MKR VIDOR 4000
Arduino UNO WiFi Rev.2
Please note: these three boards use dedicated pins to communicate and select the WiFi module, therefore you have no restriction in the usage of the available digital pins connected to the header pins.
Code
You should have access to a 802.11b/g wireless network that connects to the internet for this example. You will need to change the network settings in the sketch to correspond to your particular networks SSID.
/*
This example connects to an unencrypted Wifi network.
Then it prints the MAC address of the board,
the IP address obtained, and other network details.
