The more packages you install on your OpenWRT, the more space you need. It's useful to extend the storage capacity of your USB enabled OpenWRT router.
 
This article explain how to use a flash drive as a storage installing in TP-LINK TL-WR1043ND router. It is assumed that the router is flashed with OpenWRT. See this article if you haven't upgrade firmware to Openwrt.

16 Output Arduino Controller

The is a sketch for Arduino to communicate with computer or embedded device (eg. wireless router) using serial communication.
 
Arduino Duemilanove have 14 digital IO pins (2 digital IO used by serial) and 6 analog IO pins. Here I coded the analog IO as digital IO, so we can easily get 16 digital IO.

WinSCP (Windows Secure CoPy)

WinSCP is an open source free SFTP client, SCP client, FTPS client and FTP client for Windows.

Most people use vi as the text editor during configuration of embedded device. I hate to use vi, in which I have to memorize all the commands. Whereas WinSCP is a GUI (Graphical User Interface) program where you can edit your file like notepad. Additionally you can use WinSCP to download and upload files including settings of permission.

TP_LINK TL-WRT1043ND router and OpenWRT is use in this tutorial.

Integrating PuTTY in WinSCP

Most of the time, I use both WinSCP (Windows Secure CoPy) & PuTTY together, especially when work with Openwrt and DD-Wrt. It is very troublesome to start each program individually. So I decided to integrate PuTTY into WinSCP.

 

WinSCP is an open source free SFTP client, SCP client, FTPS client and FTP client for Windows.

http://winscp.net/

 

PuTTY is a free implementation of Telnet and SSH for Windows and Unix platforms.

http://www.chiark.greenend.org.uk/~sgtatham/putty/

 

I would suggest to download the portable version for both WinSCP & Putty. With the portable version, you can easily copy WinSCP & PuTTY from one computer to another computer without erase the settings.

Here is the link for partable WinSCP & Putty:

My previous article Control Arduino via PHP (EasyPHP) control Arduino from a computer with web server. Another article Control Arduino with TP-Link TL-WR1043ND Router which the Arduino is connecting to the router, but it is not safely to control over the internet.

 
Now I want to control Arduino without a computer and it is very safely control over the internet. Here is the step.

AppServ Web Server

Before reading this article, you may want to know EasyPHP web server that I setup previously, please refer this page http://diy2u.weebly.com/1/post/2012/07/winxp-easyphp-web-server.html.

 
I'm installing Apserv web server today (11/08/12) due to EasyPHP web server did not display any image slide from my computer.
 
I tested 4 different versions of EasyPHP from EasyPHP-5.3.9 to the latest EASYPHP 12.0, and also tested with different browsers, but I had no luck to make it work. 
 
I confirmed that it is not the Joomla problem, because the same webpages can run on my website (the webpages that you are seeing now). I suspected it must be something wrong with the library settings or the EasyPHP configuration, but I don't want to spend too much of time to figure it out.

Control Arduino via PHP (EasyPHP)

The Arduino Duemilanove (not Arduino Uno) is control by a computer over the network or internet via PHP. This article assumed that you already install WAMP web server & Arduino driver in your computer.

My Arduino Duemilanove is connecting to the USB port of my computer, the USB serial com port is detected as COM4.
