🏠 back to Observable

GPIO access?

Camera hardware, where it exists, can be accessed using WebRTC - is there an equivalent for GPIO?

I’d like to be able to access both from an Observable notebook running on my Raspberry PI. The camera access was quite straightforward as there are good examples, but I’m not getting anywhere with the GPIO.

Thanks,

Andrew

From https://www.reddit.com/r/raspberry_pi/comments/4kpa1m/how_do_i_control_rpis_gpio_via_web_browser/, it seems that you have to run a server, and then access the service from you web application / notebook. The browser cannot access directly to the GPIO.
