In a recent Adafruit order I couldn’t resist picking up the new PiGlow for the Raspberry Pi. This is a neat 18 LED add-on that connects to the GPIO header of the Raspberry Pi and communicates over I2C. With the example Python code, I was blinking in color in no time.
You can buy them from Adafruit in the US or directly from Pimoroni in the UK. The Pimoroni site has all the links to get you started. I used the link to Jason Barnett’s Gihub which has a in depth how-to and a lot of examples to get you started and playing in color.
