  1. Hi. Yesterday I built a guitar from "The Lego Mindstorms Robot Inventor Activity Book" by Daniele Benedettelli. It's a great book by the way. The best is you can actually play on this guitar.
  2. Hi. Today I built Rubik's Cube Solver for Lego Mindstorms Robot Inventor, thanks to instructions and code from David Gilday. Link to code and instructions here:
  3. No. There is one error easy to fix: AttributeError: 'MSHub' object has no attribute 'battery' This line should be removed/commented as same as its commented in my code. hub = MSHub() Best regards artpoz
  4. I think you forget to change the first parameter in function pixel(). Check below: for led_y in range (5): for led_x in range (5): if battery >= led_on_crit_full[led_y]: hub.display.pixel(led_x,led_y,9) Best regards artpoz
  5. I have been playing with the Mindstorms Robot Inventor kit (#51515) for some time. Unfortunately, it does not have a display, but it has 25 LEDs. The battery level can only be viewed on a connected device: laptop or smartphone. I wrote a short Python program that lights up 3,5,10,15,20,25 LEDs depending on the battery level. It can be uploaded let's say as the 19th program and it will stay in the hub. Maybe it will be useful to someone. Any comments and suggestions are welcome. Battery level on Mindstorms Robot Inventor
  6. I made a short tutorial how to connect a PS4 controller to a Robot Inventor. Maybe it will be useful for someone reading this topic.
