Re: Curses robot

I have got my code working. I changed so the GPIO pins were on for 0.1 seconds. It did work that way. Because if I hold the key it read an input every 0.01 secondisch and because the "else" statement killed it so quick the motors didn´t react.

What is the code supposed to do? At the moment it runs once through a sequence of calls that twiddle the status of a couple of GPIO pins. Also you've defined it to use BCM (Broadcom pin numbering). BCM GPIO13 is physical PIN#33 & BCM GPIO5 is physcial PIN#29 (on a B+) neither of those pins exis...

Scratch should be fine: I often run it that way. You need to configure your ssh connection for X-forwarding. For a command-line session, try ssh -X <user@remote_address> (Of course, you need an Xserver running on the machine from which you make the ssh connection.) I believe Minecraft expects to us...
