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.
Pimoroni PiGlow – Get visual feedback from your Pi! The PiGlow is a small add on board for the Raspberry Pi that provides 18 individually controllable LEDs. You can use it for all sorts of things! And of course, it fits inside a Pibow! (read more)
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
