Hi There -
This is awesome! I have re-learned my morse, and am playing with my Onion Omega to get it to show morse on the led when triggered via IFTTT and the Onion Cloud! (and it's amazingly seamless to use the Onion Cloud)
One thing I ran into when trying to update the "delay". I kept getting a permission denied error when trying to write a new delay to the led with the command line specified. I also noted that the address used for the delay call in the example is different than that of the actual display call. However, when I tried to set the delay with the same path as for the message, it appears to work.
i.e. I used "echo 100 > /sys/class/leds/onion:amber:system/delay" and that seems to work.
I don't know if I missed a step when trying to use the command above or not, but I wanted to post it in case anyone has encountered this as well.
Thanks again for a very entertaining way to try out my Onion Omega and the Cloud!
