28 tiny RGB LED pixels in a single row that just slip right onto your Pi's pins, no soldering required! LED SHIM is ideal for status updates, notifications, a VU meter, or as a bar graph for sensor readings.
We've created an easy installation script that will install all pre-requisites and get your LED SHIM up and running with minimal efforts. To run it, fire up Terminal which you'll find in Menu -> Accessories -> Terminal on your Raspberry Pi desktop, as illustrated below:
In the new terminal window type the command exactly as it appears below (check for typos) and follow the on-screen instructions:
curl https://get.pimoroni.com/ledshim | bash
python3 -m pip install ledshim
If you want to contribute, or like living on the edge of your seat by having the latest code, you should clone this repository, cd
to the library directory, and run:
python3 setup.py install
In all cases you will have to enable the i2c bus.
