Hello, I currently use Tasker with several plugins to timelapse a smartphone camera. I would like to make it more advanced the script, so i after i followed this tutorial: http://blog.koivistik.com/pilapserails-raspberrypi-time-lapse-rails/ i motorised a slider, install that software on raspberry pi and control the slider. What i want is, to be able to make a task from tasker, to control comunicate with gpio from raspberry pi, so i could move the slider one direction on certain time. As i saw in that software, it was comunicating trough GPIO. So ideea is: to have the phone on the slider, and control it from another phone. Tasker to do: open android camera app move slider 10cm for example stay 10seconds android camera take a picture again move slider 10cm take picture for certain amount of time Any ideea how to do that? Thank you Regards Sebastian
