Access external Scratch sensors and endpoints through python
# scratch-ext Access external locations (eg: GPIO) from scratch on the Raspberry Pi
# Running Clone the repo (or download the .tar.gz). Move the .desktop file to your desktop, and start from there, or run from a terminal inside X:
` bash ./startup.sh `
# Usage For now you can use the standard GPIO pins, broadcast a message in Scratch, saying pin 11 on will turn pin 11 high, pin 11 off will turn it low. You can also use pin 11 1, pin 11 high, etc. gpio is an alias for the ping command (eg gpio 11 on).
The script will update any changes in the gpio pins to the standard Scratch sensors. Open the ‘sensing’ tab, and select the pin you want to read from the list. This will return a 1 when high, and a 0 when low.
# Writing plugins Add a .py file to the plugins dir, extend from plugin base, and implement the receive method, see the ExamplePlugin for an example.
Download the file for your platform. If you're not sure which to choose, learn more about installing packages.
