QUESTION
I am trying to incorporate sounds in our GoPigo and I am using Python. I installed PyGame and was trying to use fadeout
but it seems not working. It doesn't generate an error but from what I am hearing when I run the code is that doesn't fade out. Any ideas
ANSWER
Answered 2019-Oct-26 at 09:28The unit of the time parameter to pygame.mixer.music.fadeout()
is milliseconds. 10 seconds are 10000 milliseconds:
QUESTION
I am using the GoPiGo3 class from GautamV/J4GPG on github to control a GoPiGo3 board from DexterIndustries. The code is not official from DexterIndustries but a java port from a python library that DexterIndustries makes.
I am just trying to test the code and cant create an instance of the GoPiGo3 class. I am using BlueJ, made a package of GautamV's code in BlueJ, and imported the GoPiGo3 class into a demo class.
My research leads me to believe that the GoPiGo3 class is designed as a singleton to ensure that only one instance is ever created and has overloaded constructors to allow for flexibility in its instantiation.
Here is relevant code from the GoPiGo class:
...ANSWER
Answered 2019-Jul-02 at 22:36As you said, its implemented using a singleton pattern, so you need to use the Instance
methods instead of constructor. Because of the private modifier on constructor private GoPiGo3(int addr, boolean detect)...
, it can only be called from within GoPiGo3 class.
QUESTION
I hope you're doing good.
I've been working on a robot for couple of months and got it working properly recently. Sadly, my code got deleted including all libraries, tried to install OpenCV couple of times but I'm still getting errors
I used this link to install OpenCV 3.4.0 with the latest version of Raspbian https://www.life2coding.com/install-opencv-3-4-0-python-3-raspberry-pi-3/
ImportError: libavcodec.so.56: cannot open shared object file: No such file or directory
Is there a proper way to install all libraries ? I'll include all libraries I used at the beginning of the code below.
Thanks in advance
...ANSWER
Answered 2018-Dec-12 at 13:24Could be that you installed an old/wrong version of opencv, or it could be that you installed the base version, without the extra modules.
I would advice installing use pip, always works for me. In that case the following command should be enough:
pip install opencv-contrib-python
Note: you need to uninstall openCV first. Read more about the installation here
If you dont know what pip is, read about it and install from here
QUESTION
I am just wondering if someone could help me out. I am controlling a robot via a Raspberry Pi, using Python and want to know how I can change the amount of time the robot moves backwards for. It's currently on half a second and I would like it to be three seconds. I have listed the code below that I am using thus far.
...ANSWER
Answered 2017-May-30 at 17:21From what I can see, time here is now ("0") plus 0.500 ("half a second"). To change to 3 secs, you need to do "now" plus "3".
Try this and let us know!
QUESTION
Is there a way to access a library that I can access on command line on python that is connected that library
One example would be

Answered 2017-Mar-23 at 21:09Look into https://docs.python.org/3/library/subprocess.html
For example, you can run the command (I have not tested this particular usage):
