			More info here: [https://learn.adafruit.com/setting-up-a-raspberry-pi-as-a-wifi-access-point]

			===Installing Requisite Software===

			Basically, you will be setting up your Pi as a host access point, which requires some software. Specifically, here is the software required:

			<pre>
			$ sudo apt-get install hostapd isc-dhcp-server
			</pre>

			===Set Up DHCP Server===

			Next, set up the DHCP server by editing <code>/etc/dhcp/dhcp.conf</code>

			Remove the following two lines by commenting them out:

			<pre>
			option domain-name "example.org";
			option domain-name-servers ns1.example.org, ns2.example.org;
			</pre>

			Next, add the word "authoritative;" to the section where it gives you information. You should see this in your file:

			<pre>
			# If this DHCP server is the official DHCP server for the local
			# network, the authoritative directive should be uncommented.
			authoritative;
			</pre>

			Finally, add the following lines to set up the IP address assignment/configuration:

			<pre>
			subnet 192.168.42.0 netmask 255.255.255.0 {
			range 192.168.42.10 192.168.42.50;
			option broadcast-address 192.168.42.255;
			option routers 192.168.42.1;
			default-lease-time 600;
			max-lease-time 7200;
			option domain-name "local";
			option domain-name-servers 8.8.8.8, 8.8.4.4;
			}
			</pre>

			===Set Up DHCP Interfaces===

			Next, edit the file <code>/etc/default/isc-dhcp-server</code> and update the <code>INTERFACES</code> section to read:

			<pre>
			INTERFACES="wlan0"
			</pre>

			Now disable the wlan0 interface:

			<pre>
			sudo ifdown wlan0
			</pre>

			Now change the wlan0 network interface so that it will use manually-assigned IP address information, instead of trying to set everything automatically. Edit <code>/etc/network/interfaces</code> and add/change the lines:

			<pre>
			# auto wlan0
			</pre>

			<pre>
			allow-hotplug wlan0

			iface wlan0 inet static
			address 192.168.42.1
			netmask 255.255.255.0
			</pre>

			Finally, edit <code>/etc/hostapd/hostapd.conf</code> to set up the wireless network:

			<pre>
			interface=wlan0
			driver=rtl871xdrv
			ssid=Pi_AP
			hw_mode=g
			channel=6
			macaddr_acl=0
			auth_algs=1
			ignore_broadcast_ssid=0
			wpa=2
			wpa_passphrase=Raspberry
			wpa_key_mgmt=WPA-PSK
			wpa_pairwise=TKIP
			rsn_pairwise=CCMP
			</pre>

			Note that the <code>driver=rtl871xdrv</code> line may need to change.

			UART = Universal Asynchronous Receive/Transmit

	While you can normally interface with and power the Pi by plugging it into a computer or a wall wart via the mini USB port, you can also power the Pi via the pins on the board, and communicate with the Pi via a serial connection. This uses the 5V, Ground, TX, and RX pins that are on the right side (the 5V side) of the pins on the Pi board.

			=Powering the Pi via UART/Serial=

			While you can normally interface with and power the Pi by plugging it into a computer or a wall wart via the mini USB port, you can also power the Pi via the pins on the board, and communicate with the Pi via a serial connection. This uses the 5V, Ground, TX, and RX pins that are on the right side (the 5V side) of the pins on the Pi board.

			By plugging these into a USB serial adapter, which is plugged into a computer, the connection can be used to provide power and a connection to the Pi.

			===Making an Internet of Things Morse Code Keyer with Raspberry Pi===

			Combining the morse code example below with [[Flask]], a lightweight web server for Python, allows us to create an API for remotely controlling the Raspberry Pi. We can then use the Raspberry Pi to send morse code with the LED.

			Here are the details: [[RaspberryPi/IoT Morse Code Keyer]]
