Connecting ULN2803 Line Driver to Arduino

If you are using Arduino (or any other TTL device) to control 4 channel relays or more, I would suggest to use ULN2803 Line Driver instead of Transistors or FETs. You can use ULN2003 which is much more cheaper if you plan to use not more than 7 channel relays.

The ULN2803 Integrated Circuit (IC) is a "Eight-way Line Driver". It allows you to interface TTL signals (5v) with higher voltage/current (50V/500ma) loads.

As shown in figure 1 and figure 2, an Arduino is control 8 relays, one using ULN2803 line driver and the other one using transistors, both circuit are equivalent.

This is an article to guide you on how to use a webcam attach to a router and act as an IP camera. At the end of the article, it show you how to adding authentication to the project.

OpenWRT in VirtualBox

If you are considering to test OpenWRT without a router or you don’t want to flash the router firmware over and over again. Here is the right place for you.

OpenWRT in VirtualBox is an image file run in VirtualBox. By the time I write this article, the VirtualBox & OpenWRT image version are Ver 4.1.20 and 10.03.1 respectively.
