Internet Control

[ninoman123]

Looking to learn a little bit about internet control of devices. Wanted to start simple like controlling a LED or something like that over the internet. Ive got experience with microcontrollers. Mainly AVR. Anybody know any websites I could start at? Ive designed a few devices that send information from a microcontroller to a PC using R232. So maybe I could start by sending that information to another computer over the internet. Any advice at all?

You would probably start by building/buying a NIC either from a chip or from a device like a XPort from Lantronix.

I was thinking something like writing a program that would send commands to another computer. This could be done using Visual Basical and the WinSock control. The receiving computer would then send the data to the AVR through RS-232 serial communication. Then the AVR would decode that data and if it was a valid command preform the task. Seems decently easy. Ive already written code to communicate between 2 computers over the internet. And Ive written code to send data to an AVR over the serial port. Just need to stick the two together lol. I need to get my programmer from school and Ill put it together and keep you guys posted.

You can definitely control your robot remotely by sitting on a remote computer by sharing the other computer with REMOTE DESKTOP connection and can send command to the robot. Many softwares like RealVNC4.1.2 helps to remotely log on to the computer and to control the same.
