YESS!!!!! I GOT IT!!!!
All I had to do was change "sd" to "sda1" when I called my python script!!! Here is the call
Process p;
p.begin("python");
p.addParameter("/mnt/sda1/arduino/www/BridgeClient_TEST/bridgeClient_python.py");
p.run();
Thank you so much for your help. I cannot express how happy I am right now
One last thing, how can I check that the python is receiving the "A0" value that is being sent?
