Filereadline Question

Recently I have been working with a text file from which I read a series of comma delimited lines. Each item represents a series of numbers, like this: 27,28,29,31,32,34,35,37,38, The problem is that the FileReadLine function strips out the commas and reads the line as one huge number.

Question: Ez-B V4 Controller Cannot Stay Connected To Wifi

I purchased an Ez-b v4 controller about a month ago to mod an Omnibot 5402 I bought from Ebay.

Galapagos Bot

The strafe buttons do not work on the Galapagos bot ARC app for the iPhone. Also is there a way to add a battery level indicator into the control panel, to be able to see a visual battery level?

4Wd Omni Wheel Drive

Question for you guys. I know we are limited to one motion panel ( h bridge or continue rot servo) per ARC, but was wondering if you could get motion from connecting opposite motors on a set up like this so, you have essentially two drive directions and then diagonal motion activating both forward and reverse.
