Control LED Using Local Wifi

We may require to transmit data from the board to other devices at some point or another.

Linkit one provides us with many options like GSM, GPRS, Bluetooth, micro SD, Audio and WiFiLinkit one has built in WiFi module, which can be used to transmit and receive data through WLAN.

Thus in ths instructable I'm gonna show you how we can control the onboard LED through local Wi-Fi.

Since Linkit one already has all the necessary hardware inbuilt, we just need to connect the WiFi/Bluetooth antenna to the board

Note: The antenna connector socket is very delicate, connect using soft hands

You will need a WiFi router (regardless of internet connection)

Once you have set up the router, note the Network SSID, the Network Password and encryption type (WPA/WEP/OPEN)

Note: Mobile hotspot will also do

I have attached my code with the instructable, you'll need to edit the Network SSID and Password with you SSID and password on line 5&6.

In the code I'm controlling the digital state of the LED through inputs provided by a host, you may edit the code to print analog inputs, inputs from sensors, or anything you can imagine to do with the board.

When you upload the code to the board, open your serial monitor

Copy the IP address that is displayed(You can now close the serial monitor and arduino software if you wish)

Paste the IP address in your browser and you may see the output like in the picture
