A red light for this green LED

Thinking about it, perhaps there's more than one kind.  Mine has four blue keys and a red key.  But I've seen another that has five blue keys (type "G"):

Perhaps I should get that one instead.

Quote:the best way would be to maintain pypilot so that a hat.conf file can specify if the keys are active high or low.
I suggest modifying the software to make the lines work for you, and post the changes "git diff"

Thanks for being open to that.  I seem to recall that the RPi GPIOs have pulldowns as well as pullups.

Quote:As for the LED, what will it do?   Just turn on when the pilot is on or should it have other functions like blinking in standby?

Could do either.  Tongue
