title: buttons for sending a 1 byte character to an ip address
body: <p>I am new to python and I am looking for a way to send a 1 byte character (for example: the letter "D") to an ip address. This is used to control a robot so all I need are forward, backward, left and right. I've done some research online and it suggests using sockets to connect to the ip address but it seems kind of confusing to me. I have made 4 buttons in my webpage already but I am not too sure on how to make the webpage send out the signal to the ip address when the user click on the button (for example: if the user press the "right" button, the webpage will send a one byte character "r" to the ip address)</p>
  
  <p>Any help would be greatly appreciated</p>
  
  <p>ps would there be any big difference between the networking method i use? like between wifi and 3G</p>
