This Python based software provides a green screen for the canoe freestyle timer (github.com/proalvo/canoe-freestyle-timer) to be used for live video streaming.

- Raspberry PI + Raspbian OS
- Disable screen saver for GUI
- Install Python 3
- Provide fixed name for the USB port
- Connect Canoe Freestyle timer to the Raspberry Pi's USB port
- Copy the freestyle-timer-green-screen.py and run it
You need to disable screen saver to have green screen visible all the time.
Original instruction at https://www.geeks3d.com/hacklab/20160108/how-to-disable-the-blank-screen-on-raspberry-pi-raspbian/
You can disable the blank screen once with the following command line instructions:
$ sudo xset s off
$ sudo xset -dpms
$ sudo xset s noblank
xset s off disable the screen saver, xset -dpms disables the DPMS (Display Power Management Signaling) and xset s noblank tells to X server to not blank the video device.
Raspberry PI will set a new port name for the USB every time you restart the Arduino UNO. Luckily there is a methods to set fixed name. See instructions at:

Note that the python script is using the port name: /dev/ttyUSB_GREENSCREEN
