Editing the crontab

Because we want want our Raspberry Pi to boot up and run our code as soon as the VTOL (or Quad-copter) is turned on, we will have to edit the crontab.

For the sake of this example, we will pretend like our code is in the file pyTest.py and saved at /home/pi/Desktop/pyprog.

In the terminal, enter the command "crontab -e" adding "sudo" before the command if it asks you if you are root.

At the bottom of this file, we would add

@reboot sudo python /home/pi/Desktop/pyprog/pyTest.py

Now, when the Raspberry Pi is turned on, the script(s) specified should be run automatically.
