Pimoroni released the PiGlow in August while I was away in Poland. It’s a small, purple board (that fits inside a PiBow) with 18 LEDs in 6 colour groups, arranged in a 3 armed spiral formation. It has an 8 bit, 18-way PWM controller that can be used to control the brightness of the LEDs (0 = OFF, 255 = Fully ON). (More on PWM here)
Although I was abroad when it came out, there was plenty of banter about it on twitter. In a few short weeks, various people have written Python classes to make it easier for us to use the PiGlow board with Python.
Once I can get the latest WiringPi2 Python up and running, I’ll give it a shot with that, but for the time being, I thought it’d be fun to code around Ben Leb’s “PyGlow” class and combine it with some RPi.GPIO interrupts, some buttons and a couple of my own PCB prototypes.
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)
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
