I'm making a robot using a Raspberry Pi.
I have written code for it in Python and I would like the Python script to run as soon as the Pi is powered.
I only want the whole script to repeat the whole time.
Boot Options then
Then in a Terminal window run:
sudo nano /etc/profile
At the bottom add:
sudo python /home/pi/yourscript.py
Press ctrl+X and then press Y followed by ENTER twice.
/home/pi/ is the directory of your python file and
yourscript.py is the name of your python code.
To check this works reboot the Pi. If you want the Python code to repeat, in your Python code set up some kind of While loop and that would work. Alternatively you could look into using Cron. However, depending on how you coded you program it might run indefinitely anyway.
I would use a Cron Job:
( sudo crontab -l; echo "@reboot" $(which python) /home/pi/foo ) | sudo crontab -
If your sketch doesn't need to be run as root, you can omit both
sudo parts and run it as your current user, at boot.
/home/pi/foo with the full path to your python sketch. The
@reboot will run the path to your sketch in your current version of Python, upon a complete reboot.
