The current BoneScript library tries to load a device tree overlay to enable the GPIO pin mode. That might cause it to have some delay or not work the first time you try. The roadmap to fix this is to switch to cape-universal. That'll be included in the next BoneScript release. If it works directly with the BoneScript library, it should work the same via the web interface. All the calls on the web interface are asynchronous, however, so you might be calling them before the pinMode completes. > > > On Saturday, November 15, 2014 10:27:53 PM UTC-8, John Mladenik wrote: >> >> I have tried at least 6 different tutorials to turn an LED on and off >> through a web page.
