PingMonitor - Monitor your ping times using LedBorg

This is an old driver based LedBorg script
We recommend using the new driver free based scripts for LedBorg.
The new driver free examples can be found here, the installation can be found here.

Ever wanted to check ping times using your Raspberry Pi, maybe check if a game server is good, or simply check your internet connection?
Well now you can some ping times using your LedBorg with PingMonitor.py, it pings a server and displays the ping against a target result visually:

0% to 22%

23% to 44%

45% to 67%

68% to 89%

90% to 110% target :)

111% to 132%

133% to 155%

156% to 177%

178% or more

Timeout or failed

There are some settings you may wish to change:

• pingAddress, line 17
  Sets the server address (name or IP) to ping
• targetPing, line 18
  The target ping time, in milliseconds
• delayInterval, line 19
  The time to wait between pings, in seconds
• colourTimeout, line 16
  The colour to use if a ping times out or has an error
• colourGrade, line 15
  The colour gradient to use, from 0% to 200% of targetPing

Here's the code, you can download the PingMonitor script file as text here
Save the text file on your pi as PingMonitor.py
Make the script executable using
chmod +x PingMonitor.py
and run using
./PingMonitor.py
