gpiowebhook
This is a tiny HTTP server for toggling GPIO pins via HTTP requests.
The current version calls mraa-gpio to do the toggling.
Use
Run this on the SBC:
KEY=secretkey ./gpiowebhook
This starts a HTTP server on port 28384. Now make a HTTP request like so:
curl http://localhost:28384/?key=secretkey
The server will then set pin #11 to HIGH, wait 100ms, then set it to LOW.
Hook up something to the pins and you can now control it over HTTP. In my case, I jerry-rigged a transmitter of an electric gate opener.
Proof-of-concept:
