Simultaneously displays the Ping status of Multiple IP addresses on a 4x8 RGB LED array that updates every two seconds
Now when somebody says that, you can have an indicator to show you what's happening. All red LEDs means your internet connection really is down. Watch your internet service quality change, even when you are not actively online
Every two seconds the software pings a list of IP addresses or domain names. The response times of each ping are indicated on the LEDs, one LED per item in the list. Green is for fast, green-yellow and yellow for slower, orange and red for slow to none.
Here I have set the top line to be my local routers. The first LED is my WiFi router, then the LEDs to the right of it are routers of my ISP. The LEDs on the bottom are specific websites. Any LED can be left blank by entering a NULL item in the list.
Adafruit Feather HUZZAH with ESP8266 WiFi
https://www.adafruit.com/products/2821
NeoPixel FeatherWing - 4x8 RGB LED
https://www.adafruit.com/products/2945
These are WS2812 LEDs. The data signal is sent on pin 13 of the ESP8266.
Note: The default pin on the FeatherWing does not work with the ESP8266.
The jumper on the back of the wing must be cut then another jumper
must be shorted with a blob of solder. I used pin 13.
Sites to ping must be listed in the source code before compilation
I prefer to have the first line of eight LEDs are my ISP's routers to the internet.
Use the traceroute utility to find these routers. Traceroute lists all of the routers in line to the source.
Line 1 192.168.1.1 is the WiFi router.
Line 2 xe-9-1-3-sur02.boulder.co.denver.comcast.net (68.86.129.29) is the name and IP address of the first
router of my ISP.

The routers can be set by name or IP address. From line 2 above xe-9-1-3-sur02.boulder.co.denver.comcast.net
works as does 68.86.129.29. NULL entries represent blank LEDs.
The rest of the LEDs are websites

Once you list the sites, compile and upload to the ESP8266
The list of IP addresses or domain names is fixed at compile time.
