I get the following error when i run rc_control_test.py

(auto-rccar) akash@asp:~/Downloads/AutoRCCar-master/test$ python rc_control_test.py
pygame 1.9.4
Hello from the pygame community. https://www.pygame.org/contribute.html

During handling of the above exception, another exception occurred:

I was having similar port permission issue while burning Arduino code but somehow managed to fix it.
Please help me to fix this issue now. Pygame opens and closes abruptly.
Port Permission denied it says

You first check what is currently selected for the port in Arduino IDE. Then give the same instead of /dev/ttyACM0 in rc_control_test.py. Doing this just solved my problem.

Now serial port isn't visible in Arduino ide. It shows the same Port in the bottom left corner though. Thanks.. I'll try to fix this and let you know
