You can now control your RC car, but you certainly want to do this without any connected cables. This section will show you how to add a wireless LAN device so that you can control your car remotely. In Chapter 1, Getting Started with Raspberry Pi Zero, you learned how to access Raspberry Pi Zero from a host computer. However, for this to work you need your Raspberry Pi Zero to be connected to a network, either with a LAN cable or a wireless network. What if you want to drive your car where there is no network, but still connect to it? You can do this by making your Raspberry Pi Zero a wireless access point.
Setting up Raspberry Pi Zero as a WLAN access point depends upon the USB WLAN adapter you choose; see http://elinux.org/RPI-Wireless-Hotspot for some of the devices supported and how to configure them. I chose the Edimax USB WLAN adapter, pictured here:
This device can be configured using the script found at http://blog.sip2serve.com/post/48899893167/rtl8188...
