This folder contains several demo programs that you can use to help you in developing your own code. Brief descriptions of each demo are provided below; you can access the full source code and some more detailed information on each by opening the respective folders above.
To install these on your EV3, use git to clone the ev3dev-lang-python-demo repository from github. Your EV3 will need Internet connectivty in order to clone the repository from github.
$ sudo apt-get install git
$ git clone https://github.com/ev3dev/ev3dev-lang-python-demo.git
There are two ways to run a program. You can run a program from the command line or from the brickman interface.
Note that for both running from the command line and running from Brickman the
program must be marked as an executable and the first line of the program
must be #!/usr/bin/env python3. To mark a program as executable run
chmod +x PROGRAM_NAME.py. All of the demo programs are already marked as
executable and already have #!/usr/bin/env python3 so you should be fine, we
only mention it so you know to do these things when writing your own programs.
To run one of the demo programs from the command line, cd to the directory and
run the program via ./PROGRAM_NAME.py. Example:
$ cd ~/ev3dev-lang-python-demo/robots/R3PTAR/
$ ./r3ptar.py
To run one of the demo programs from Brickman, select the program in the File Browser.
Laurens Valk's BALANC3R - This robot uses the gyro sensor to balance on two wheels. Use the IR remote to control BALANC3R

- EV3D4RemoteControl - Use the IR remote to control EV3D4
- EV3D4WebControl - Use a web interface to control EV3D4. There is a desktop version and a mobile version, both support touchscreen so you can drive via your smartphone. The web server will listen on port 8000 so go to http://x.x.x.x:8000/
