Hello everyone,
I was wondering what's the most easiest way to use an external trigger (e.g. a single button on a USB cable would do the trick for me) within app inventor.
So far I using a workaround, where I use the proximity sensor of my phone to be able to use it as a switch whenever I put something above it. Some other sensors could be used to trigger an event aswell, but all of them are internal.
I'm just looking for a way to implement an external input signal. Maybe there are ready made components (e.g. headphones with a button) that will work for me. It would be nice to avoid using an arduino and communicate via USB serial.
Many thanks!
