OpenWRT in Client Mode

Client mode uses its wireless connection as the WAN interface, and shares the internet connection only to the LAN ports. It is not seen as an access point by laptops or other computers scanning for AP's and does not accept wireless connections from client devices.
 
As shown in figure below, the new SSID (wwan) cannot be seen by other client devices nor accept wireless connection from client devices. Therefore the client devices (Notebook3 and Notebook4) must connect to the Wifi router using network cable.

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.
