![]() If you use it and like it, drop me a comment and let me know :) I've uploaded my code here if anyone wants to do something similar. ![]() the Pi0 is shutdown) the lights are turned off safely. I made a simple python script which runs on boot and displays pulsing red lights until it detects emulation-station is running, then flashes green. Test your connections, fix any issues and try again. If it still doesn't show up, then you may have a problem with your soldered joints. Which should show the address of the LED shim (0x75). If you have any problems, I'd start by ensuring the LED shim is detected over I2C: i2cdetect -y 1 ![]() When complete you'll have a directory in /home/pi with a bunch of helpful examples to get you started with lighting up some rainbows! Before you go any further I'd check that you can run some of these example scripts and all is OK. Next install the Pimoroni LED shim library and all its dependencies with: curl | bash Once logged in, execute "passwd" to change it. SSH onto the Pi0 ssh default password is "raspberry". If you get stuck - go back to the RetroPie/Emulation-Station docs or give it a quick google. I'm going to assume you've now booted up the Pi0, set it all up and enabled WiFi. You can also setup WiFi from the Emulation-station menus, so it's up to you really how you do it! Just don't forget to connect to the computer via the data USB port on the Pi0, not the power one! I do this because it makes it simple to connect the Pi0 to your computer via USB and ssh onto it - particularly before you've setup wifi for the first time.
