The AUR arduino package will not work since it is version 1.0.6! You need to install 1.5.8 from the or if you have a. You will also need the latest Digispark files that you can get by: git clone Unpack the Arduino zip to a folder of your choice and copy the digistump folder from /hardware in your git clone to /Arduino/arduino-1.5.8/hardware/ Unpack the zip for your architecture in /Arduino/arduino-1.5.8/hardware/digistump/avr/tools/ It will be either linux32binaries.tar or linux64binaries.tar You will also need the 0.1 version of the libusb library which you can get on Arch by sudo pacman -S libusb-compat The last part is getting the micronucleus to work. For this (at least on 64 bit systems), you can install the AUR package or compile it yourself.
Git clone cd micronucleus/commandline make Copy the resulting micronucleus executable into /Arduino/arduino-1.5.8/hardware/digistump/avr/tools/ and you should be good to go. Also take care of the udev rules, as with all other Linux distributions.
