I am making a project which contains face and object recognition. I activated functions with push button. My question is how can i run automatically my GPIO script when reboot raspberry.
I've tried write in .bashrc file. But it causes error(i guess its about camera) that;
mmal: mmal_vc_component_enable: failed to enable component: ENOSPC mmal: camera component couldn't be enabled.
Do you have any suggestions?
You can do this quite easily by adding a line to your crontab file. Do this:
From your $ shell prompt, enter man crontab. Read what it says. When you finish, dismiss the man page be entering q, and then enter crontab -e on the command line.
The nano editor will start, and show you a "default" crontab in which each line is commented - it begins with "#". Using nano, move the insertion point to the first new line at the end of the file. Enter this:
@reboot /usr/bin/python3 ~/somefolder/somefile.py &
Where ~/ is your home directory (probably /home/pi), "somefolder" is a folder in your home directory containing the Python script you want to run, and "somefile.py" is your Python script. The & lets your Python script run "in the background", and doesn't hold things up.
After you've added this line, use nano's Write (^O) to save the file, and accept whatever filename it suggests. Then exit nano using ^X. You'll get a confirmation message that your crontab file has been updated.
Reboot your pi, and your Python script will execute; and it will execute each time your pi reboots.

If you get stuck with a specific problem on this I can help you. To give you an idea you can look at this example for a systemd service. And please take the Tour. – Ingo Apr 20 '18 at 12:58
