Bright LED arrow/pointer prototyped on a Raspberry Pi and run with a Wemos ESP8266 board

 

Alex Eames, who was covered in a community profile yesterday, has used his RasPiO Inspiring system of bright LEDs in geometric shapes to create an illuminated pointing sign. He’s blogged about the mini-project, which involved some foam board, some sewing and, eventually, an ESP8266 Wemos board (he started out by prototyping the code in Python on a Raspberry Pi and then ported it to the Arduino-like Wemos). You can read about the work that went into the sign here and take a look at RasPiO Inspiring here. You can see the results in the GIF below, but you can also see a video of it working here.
